Introduction

Warnings and

Precautions

The GPS system is operated by the United States government, which is solely responsible for its accuracy

and maintenance. The system is subject to changes which could affect the accuracy and performance of all GPS

equipment. Although the Garmin GPSMAP 182/182C/232 is a precision electronic NAVigation AID (NAVAID),

any NAVAID can be misused or misinterpreted and, therefore, become unsafe.

The electronic chart is an aid to navigation and is designed to facilitate the use of authorized government

charts, not replace them. Only ofﬁ cial government charts and notices to mariners contain all information needed

for safe navigation – and, as always, the user is responsible for their prudent use.

Use the GPSMAP 182/182C/232 at your own risk. To reduce the risk of unsafe operation, carefully review

and understand all aspects of this Owner’s Manual—and thoroughly practice operation using the simulator

mode prior to actual use. When in actual use, carefully compare indications from the GPSMAP 182/182C/232 to

all available navigation sources, including the information from other NAVAIDs, visual sightings, charts, etc. For

safety, always resolve any discrepancies before continuing navigation.

FCC Compliance

The GPSMAP 182/182C/232 complies with Part 15 of the FCC interference limits for Class B digital devices

FOR HOME OR OFFICE USE. These limits are designed to provide reasonable protection against harmful

interference in a residential installation, and are more stringent than “outdoor” requirements. Operation of this

device is subject to the following conditions: (1) This device may not cause harmful interference, and (2) this

device must accept any interference received, including interference that may cause undesired operation. This

equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance

with the instructions, may cause harmful interference to radio communications. However, there is no guarantee

that interference will not occur in a particular installation. If this equipment does cause harmful interference

to radio or television reception, which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the

receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an

outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced

radio/TV technician for help.

The GPSMAP 182/182C/232 does not contain any user-serviceable parts. Repairs should only be made by

an authorized Garmin service center. Unauthorized repairs or modiﬁ cations could result in permanent damage

to the equipment, and void your warranty and your authority to operate this device under Part 15 regulations.

CAUTION: IT IS THE USER’S RESPONSIBILITY TO

USE THIS PRODUCT PRUDENTLY. THIS PRODUCT IS

INTENDED TO BE USED ONLY AS A NAVIGATIONAL

AID AND MUST NOT BE USED FOR ANY PURPOSE

REQUIRING PRECISE MEASUREMENT OF DIREC-

TION, DISTANCE, LOCATION, OR TOPOGRAPHY.

MAP DATA INFORMATION: One of the goals of

Garmin is to provide customers with the most complete and

accurate cartography that is available to us at a reasonable

cost. We use a combination of governmental and private

data sources, which we identify (as required) in product lit-

erature and copyright messages displayed to the consumer.

Virtually all data sources contain inaccurate or incomplete

data to some degree. This is particularly true outside the

United States, where complete and accurate digital data is

either not available or prohibitively expensive.

WARNING: This product, its packaging, and its compo-

nents contain chemicals known to the State of California

to cause cancer, birth defects, or reproductive harm. This

Notice is being provided in accordance with California’s

Proposition 65. If you have any questions or would like

additional information, please refer to our web site at http:

Initializing the Receiver

Getting Started

The GPSMAP 182/182C/232’s advanced keypad system is designed to allow for fast, convenient

selection of navigation options and data entry. The Getting Started Tour will introduce you to the

keypad and provide a ‘hands-on’ lesson in using the GPSMAP 182/182C/232. We strongly encourage

you to take the Getting Started tour before using your unit for actual navigation.

The GPSMAP 182/182C/232 Quick Reference Guide contains helpful tips on using the unit and

performing various navigation tasks. It’s a good idea to keep the Quick Reference Guide nearby when-

ever you’re operating your new GPSMAP 182/182C/232.

Initializing the Receiver

The ﬁ rst time you power up your new GPSMAP 182/182C/232, the receiver must be given an

opportunity to collect satellite data and establish its present position. To ensure proper initialization,

the GPSMAP 182/182C/232 is shipped from the factory in AutoLocate mode, which will allow the

receiver to “ﬁ nd itself” anywhere in the world. To speed up the initialization process, we recommend

using the graphic initialization process described on the next page, which will usually provide a posi-

tion ﬁ x within a few minutes.

Before you initialize, make sure the GPSMAP 182/182C/232 unit and antenna have been correctly

installed on your vessel according to the instructions in Appendix H. The antenna needs to be in a

location with a clear and unobstructed view of the sky to receive satellite signals.

To turn the GPSMAP 182/182C/232 on:

1. Press and hold the POWER key until the power tone sounds and the display comes on, then

release the POWER key.

A warning page will appear, asking you to read and acknowledge important information regarding

the proper use of the unit.

To acknowledge the warning:

1. After reading the warning, press the ENTER/MARK key if you agree.

Initializing the Receiver

To graphically initialize the GPSMAP 182/182C/232:

1. Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until

the ‘GPS’ tab is highlighted, then press the MENU key once.

2. Using the ARROW KEYPAD, highlight ‘Initialize Position’ and press ENTER/MARK to initialize

the receiver from the map. The Initialize Position Page will appear, prompting you to select your

approximate location with the map cursor.

3. Use the ARROW KEYPAD to move the map cursor and point to your approximate location within

200 miles. If you have difﬁ culty identifying your position, press and release the IN key to see the

next lower map scale.

4. Once you have determined your approximate location on the map, press the ENTER/MARK key.

This does not “calibrate” the unit in any way, but rather helps to speed up the initial

satellite acquisition. If the unit displays “Ready (2D) or (3D )” during this process, it is

not necessary to initialize the unit.

The GPSMAP 182/182C/232 will now begin searching for the appropriate satellites for your region

and should acquire a ﬁ x within a few minutes. When viewing the ‘GPS’ tab on the Main Menu, a signal

strength bar for each satellite in view will appear on the bottom of the page, with the appropriate satel-

lite number under each bar. The progress of satellite acquisition is shown in three stages:

• No signal strength bars— the receiver is looking for the satellites indicated.

• Hollow signal strength bars— the receiver has found the indicated satellite(s) and is collecting data.

• Solid signal strength bars— the receiver has collected the necessary data and the satellite(s) are

ready for use.

Once the receiver has collected information from at least three satellites, the top of the screen will

display either “Ready (2D or 3D)”, and the GPSMAP 182/182C/232 is ready for use.

Point to your approxi-

mate location and press

ENTER/MARK.

A satellite’s strength bars

will turn black when it’s

ready for use.

GPSMAP 182/182C/232 Getting Started Tour

The Garmin GPSMAP 182/182C/232 is a powerful electronic navigation system that provides

detailed map coverage and convenient control of many advanced features right from the screen display.

This tour is designed to take you through the basic pages and functions of the system using the simula-

tor mode. Once you’re familiar with the main pages and functions of the unit, refer to the reference sec-

tion for instructions on performing speciﬁ c tasks and functions. For GSD 20 sonar related operations,

refer to “GSD 20 Sounder Module with Garmin Chartplotters” (190-00241-03).

The Getting Started Tour assumes that the receiver has been properly installed and initialized, and

you have not changed any of the default unit settings. If you have changed any settings (position for-

mats, units of measure, etc.), the descriptions and pictures in the tour may not match your conﬁ gura-

tion.

To turn the GPSMAP 182/182C/232 on:

Map Page

The Map Page is one of six main pages used in the GPSMAP 182/182C/232’s system. The six main

pages are the Map Page, Sonar Page (If equipped with GSD 20. For GSD 20 sonar related operations, refer

to “GSD 20 Sounder Module with Garmin Chartplotters” (190-00241-03)

), Compass Page, Numbers Page,

Highway Page, and Active Route Page. All ﬁ ve pages are linked together in a simple chain, which allows

you to scroll through the pages in either direction using the PAGE and QUIT keys.

The GPSMAP 182/182C/232’s Map Page combines digital chartplotting with a user-selectable

display of navigation data and a built-in worldwide database. It will also be the page you use most to

create and edit waypoints and routes. Before we take off on our practice route, let’s take a brief look at its

various features and displays.

The map display shows your “boat” as a triangle marker on an electronically generated chart.

Geographic names, roads, markers and buoys that are provided by the optional BlueChart or MapSource

data are also shown. It also displays your track, routes and nearby waypoints. An on-screen cursor

lets you pan to other map areas, determine the range and bearing to a position, and perform various

waypoint and route functions.

The data window, located at the top of the page, provides a user-selectable display of various naviga-

tion data, including speed over ground, distance to the next navigation point, compass ribbon and

current position coordinates. The current map scale setting is located at the bottom right of the page.

Map Cursor

Using the Map Cursor

Working from the Map Page is a simple process that centers around the use of the cursor.

Controlled by the ARROW KEYPAD, the cursor is an important tool that can be used to pan to

other map locations, mark and edit waypoints and routes, and review position data of on-screen map

items and waypoints.

To get a feel for using the Map Page and using the cursor, try the following exercise:

1. Use the IN/OUT keys to set the map scale to the 50 nm setting. Your boat should be near the center

of the map, at the receiver’s last known position. (If your boat isn’t where it should be, make sure

that you have initialized the receiver and acquired a position as described on pages 1-2.)

2. Use the ARROW KEYPAD to move the cursor. Notice how another data ﬁ eld appears, showing

the bearing and distance from your boat to the cursor, along with the latitude/longitude of the

cursor.

3. Press the QUIT key to remove the cursor and re-center your boat on the map display.

As you become more familiar with the cursor, you’ll see that the map display actively scrolls or

‘pans’, letting you explore areas around the world and create waypoints and routes. Wherever you

move the cursor, you’ll always be just one QUIT keystroke away from returning the map to your

present position.

Now that you’ve seen how the Map Page can be used to monitor your present location, let’s take a

minute to learn how to mark and store your present position as a waypoint. (Since you’re in simulator

mode, the present position displayed will be the last position calculated by the receiver, which should

be the spot where you’ve initialized the unit.) This will also give you an opportunity to see how the

GPSMAP 182/182C/232’s keypad and ENTER/MARK key are used for data entry and changing the

waypoint name and symbol.

Marking Waypoints

To mark your present position:

1. Hold down the ENTER/MARK key until the ‘New Waypoint’ window appears then release the

key. The window will show a default three-digit waypoint name/number (001), symbol (dot), and

position. You can leave the name as the auto-assigned number, but for this exercise, lets change

the name to ‘DOCK’.

2. Use the ARROW KEYPAD to highlight the waypoint name ﬁ eld (001) and press ENTER/MARK.

You will see that just the ﬁ rst ‘0’ is now highlighted.

3. Press LEFT on the ARROW KEYPAD to clear the name ﬁ eld.

4. Press UP or DOWN on of the ARROW KEYPAD until the letter ‘D’ appears, and then press RIGHT

to go to the next space to the right, then UP or DOWN again until ‘O’ appears. Repeat this until you

have entered the name ‘DOCK’. If you make a mistake and select an incorrect character, simply press

LEFT on the ARROW KEYPAD to backspace the cursor and then UP or DOWN to correct the entry.

(If you accidentally press ENTER/MARK before you are done, simply press ENTER/MARK again

and move the highlight to where you left off.)

5. After you have entered all the letters, press ENTER/MARK to conﬁ rm the name.

6. To access the waypoint symbol page, highlight the waypoint symbol ﬁ eld which is to the left of the

waypoint’s name and press ENTER/MARK. Note: The default symbol is a dot.

7. You will see an alphabetical list of available waypoint symbols to choose from. Press the ARROW

KEYPAD UP or DOWN until you highlight the ‘ANCHOR’ symbol. You will see a scroll bar on the

right of the window indicating your current position on the entire list of symbols.

8. Press ENTER/MARK to conﬁ rm the ‘ANCHOR’ symbol.

9. Highlight ‘OK’ at the bottom of the window and press ENTER/MARK again to conﬁ rm the ‘OK’

prompt and save the waypoint.

The waypoint is now stored in memory. Note that waypoints may also be created graphically from

the map display or by manually entering position coordinates. Each of these techniques is described in

the reference section of the manual and/or on your GPSMAP 182/182C/232 Quick Reference Guide.

Using the NAV Key

Going to a Destination

GPS is all about marking positions as waypoints and navigating to them using the receiver’s steering

guidance and map displays. We’ve already seen how to use the ENTER/MARK key to store our present

position, so it’s time to move on to the fun part—going to a destination.

The NAV key, located on the keypad above the QUIT key, is the primary tool used to select a

destination waypoint, TracBack, or a route to navigate. The NAV key can be used in two primary

ways:

• Pressing NAV once displays a list of options from which you can select ‘Go To Point’, ‘Follow Route’,

‘Follow Track’, or ‘Stop Navigation’.

• Highlighting an on-screen waypoint or map item as a destination directly from the Map Page and

pressing NAV allows you to graphically select points to “Go To”.

For our simulated trip, you’re going to select a pre-programmed tour route using the ﬁ rst method.

This will also show how the MENU key is used throughout the GPSMAP 182/182C/232 system to

provide tab style options and functions. Let’s start by changing the position to where the practice route

is located.

To change the GPSMAP 182/182C/232 position in simulator mode:

1. Press the MENU key twice to display the list of Main Menu tab items.

2. Use the UP or DOWN arrow of the ARROW KEYPAD to highlight the ‘Systm’ tab.

3. Highlight ‘Set Position’ in the simulator setup window and press ENTER/MARK.

4. From the Initialize Position page, press the MENU key. You will see ‘Enter As Text’ highlighted,

then press ENTER/MARK.

5. On the Enter Position window, press ENTER/MARK then use the ARROW KEYPAD to enter

N34°56.800’, W076°24.066’ and press ENTER/MARK when done, then press QUIT to return

To activate the practice route stored in memory for navigation:

1. Press NAV. The option list page will appear. (If we were selecting a single waypoint to navigate

to rather than a route, we could highlight the waypoint on the map, press NAV and then press

ENTER/MARK.)

2. Use the ARROW KEYPAD to highlight the ‘Follow Route’ option. Press ENTER/MARK to conﬁ rm.

3. The Select Route page will appear, with the ‘GPSMAP TOUR’ route highlighted.

4. Press ENTER/MARK then highlight ‘Activate’ and press ENTER/MARK again.

To zoom in to a closer map scale:

1. Repeatedly press the IN key until you select the 3 nm scale.

You may also hold the IN or OUT keys down to quickly scroll through the map scales. The

Map Page should now display ﬁ ve waypoints chained together in a simple route, with your boat at

the ﬁ rst route waypoint.

A data ﬁ eld at the top of the page will now display the speed, distance to the second route

waypoint, your position coordinates and a compass ribbon which shows you which way to go. To get

started, let’s enter a speed for our vessel, which we can do from the Main Menu Page.

To enter a boat speed:

1. Press the MENU key twice to display the Main Menu Page.

2. Use the ARROW KEYPAD to highlight the ‘Systm’ tab, then press RIGHT then DOWN until the ﬁ eld

below the word ‘Speed’ is highlighted and press ENTER/MARK.

3. Use the ARROW KEYPAD to enter a speed of 60 knots.

4. Press ENTER/MARK to ﬁ nish, and QUIT until you return to the Map Page.

Once a speed has been entered, you’ll notice that the map will automatically begin to move slowly,

keeping your boat centered on the display. The direction of movement, also called ‘track’, will be

controlled by the simulator.

The Set Position, Track

Reviewing/Creating

Map Waypoints

You’ll now have a clearer picture of the route you are navigating. Keep in mind that whenever you

do exceed the usable range of the built-in database or the optional MapSource or BlueChart data in use,

the range ﬁ eld will display ‘OVERZOOM’ to indicate that you should exercise extreme caution using the

map data. Press the IN key to zoom into the 2 nm scale. Now that you’ve zoomed in a little closer to

your route, you can pan ahead of your vessel with the cursor to review map items and create on-screen

waypoints. Try moving the cursor to highlight the ‘TOUR3’ waypoint— just use the ARROW KEYPAD

to move the cursor as close as possible to the waypoint. (To move the cursor in small increments, try

a series of short key presses.)

Once the cursor is over the TOUR3 waypoint, you’ll notice that the waypoint symbol and name will

become highlighted. The data ﬁ eld at the top of the page will display the waypoint name, the range and

bearing from your present position, and the coordinates for the waypoint.

To review the waypoint page for a selected waypoint:

1. Press the ENTER/MARK key.

2. To return to the Map Page, press ENTER/MARK again or press QUIT.

The cursor can also be used to create new waypoints right from the map display.

To create a new waypoint using the cursor:

1. Use the ARROW KEYPAD to move the cursor as close as possible to the following position:

N35º 02.914; W 076º 26.152’ (Use the data window to verify the cursor position.)

2. Press and release the ENTER/MARK key to capture the cursor position. Do not hold the button

down, as doing so will mark your present position, not the map position.

3. Use the ARROW KEYPAD to highlight the waypoint symbol ﬁ eld to the left of the waypoint

name/number.

4. Press ENTER/MARK to access the symbol page.

5. Press UP or DOWN on the ARROW KEYPAD to select the ‘Shipwreck’ symbol and press

ENTER/MARK to conﬁ rm.

6. Highlight ‘OK’ at the bottom and ENTER/MARK again to ﬁ nish.

The waypoint will ‘highlight’

when the cursor is moved

over it.

Waypoint numbering

will start with 001 and

continually count up,

Compass/Numbers

Navigation Pages

Now that we’re navigating to an actual destination, let’s move on to the GPSMAP 182/182C/232

navigation pages by pressing the PAGE key.

The Compass Page provides graphic steering guidance to a destination waypoint, with an emphasis

on the bearing to your destination and current direction of travel. The middle of the page features a

rotating ‘compass ring’ that shows your course over ground (track) while you’re moving, and a bearing

pointer that indicates the direction of the destination (bearing) relative to the course over ground.

The compass ring and pointer arrow work independently to show—at a glance—the direction of your

movement and the direction to your destination. For instance, if the arrow points up, you are going

directly to the waypoint. If the arrow points any direction other than up, turn toward the arrow until it

points up—then continue in that direction.

The current speed, distance to the next waypoint, turn angle and current position are displayed

at the top of the screen. This page provides better steering guidance when travelling at slower speeds

and/or when making frequent directional changes. When you are not navigating to a waypoint, the

compass will show your direction of travel as you move but the arrow will not appear.

Press PAGE to see the next page appearing in the main sequence, the Numbers Page. The

Numbers Page allows for precision navigation to 1 degree of steerage. The default page will display 3

large numbers ﬁ elds. You may customize the Numbers Page to display the size and number of ﬁ elds

along with the type data you wish to see. (See pages 22-23 for changing the types of data.)

To split the data ﬁ elds:

1. Press MENU, then press ENTER/MARK. Highlight the ‘SPEED’ data ﬁ eld and press MENU.

2. Highlight ‘Split Numbers’, then press ENTER/MARK. You will now see four new data ﬁ elds. Press

QUIT when done.

3. To return to the original conﬁ guration, repeat the above steps, but instead of ‘Split Number’, select

either ‘Merge Numbers’ or ‘Defaults’. Press QUIT when done.

Highway Page

The GPSMAP 182/182C/232’s Highway Page also provides graphic steering guidance to a destina-

tion waypoint, placing greater emphasis on the straight-line desired course and the distance and direc-

tion you are off course. As you head toward your destination, the middle of the screen provides visual

guidance to your waypoint on a moving graphic “highway.” Your present position is at the bottom

center of the highway display. The line down the middle of the highway represents your desired course.

As you navigate toward a waypoint, the highway will actually move—indicating the direction you’re off

course. To stay on course, simply steer toward the center of the highway or “keep it on the road”. The

four default data ﬁ elds at the top of the page indicate ‘Speed’ and ‘Distance To Next’ point, along with

‘To Course’ which shows the bearing to get you back on course and ‘Time To Next’ point. Additionally,

a compass ribbon is displayed to show your current heading along with a dark, vertical bar which will

indicate the direct bearing to the navigation point. When the dark, vertical indicator (or arrow) lines

up with the lighter red bar in the middle, you are heading directly to the navigation point. Use the

Highway Page as your primary navigation page (in lieu of the Compass Page) when your main concern

is following a deﬁ ned course.

Whenever the GPSMAP 182/182C/232 is in simulator mode, you can also adjust your speed and

course from the Highway Page using the ARROW KEYPAD. As you head toward each waypoint in the

tour route, try adjusting your boat speed and course to get a feel for how the highway works.

To adjust the simulated boat speed/heading from the Highway Page:

1. Press the UP arrow of the ARROW KEYPAD to increase the speed in 10 knot/kph/mph increments.

Press the DOWN arrow to decrease the speed in the same increments. Press the LEFT and RIGHT

arrows of the ARROW KEYPAD to steer the boat.

Notice that as you get off course, the highway will move to give you graphic guidance to get

back on course. You can zoom in or out on the Highway display for a smaller or larger view. Five

available settings range from 1X to 16X, with a default setting of 8X. The current scale will appear

in the bottom right of the display.

To zoom in or out on the highway display:

1. Press either the IN or OUT key to increase or decrease the zoom scale.

Map Page

The GPSMAP 182/182C/232’s Map Page provides a comprehensive display of electronic car-

tography, plotting and navigational data. When using the unit with the optional BlueChart data or

MapSource software, the map display shows your boat on a digital chart, complete with geographic

names, map items, navaids and a host of other chart features. It also plots your track and displays any

routes and waypoints you create. An on-screen cursor lets you pan and scroll to other map areas, deter-

mine the distance and bearing to a position, and perform various route and waypoint functions.

When the cursor is active, an additional data window will appear below the data ﬁ elds to indicate

the position, range and bearing to the cursor or a selected waypoint or map item. The map scale

displays at the bottom right of the page.

The (ZOOM) IN and (ZOOM) OUT keys, combined with the ARROW KEYPAD, let you select

zoom ranges and move the cursor. Two basic map operating modes, position mode and cursor mode,

determine what cartography is shown on the map display. Position mode pans the cartography to keep

the present position marker within the display area, while cursor mode pans the cartography to keep

the cursor within the display area.

The GPSMAP system will always power up in the position mode, with your vessel centered on

the map display.

• When sufﬁ cient map coverage is not available to keep the boat centered, the boat icon will move

toward the edge of the display.

When the ARROW KEYPAD is pressed, the GPSMAP 182/182C/232 will enter cursor mode. In

cursor mode:

• The cursor can be moved over the map display using the ARROW KEYPAD.

• Whenever the cursor reaches the edge of the display, the map will scroll forward under the cursor.

Keep in mind that the boat icon will move with the map scrolling and may go off the display

screen (you may not be able to see your present position).

Map Page Cursor

• When the cursor is stationary, a ﬁ xed coordinate position will appear in the position ﬁ eld. Note that

the distance and bearing will change as the boat’s position changes.

• Whenever you zoom in cursor mode, the cursor will be centered on screen.

• To return to position mode, press the QUIT key.

When the cursor reaches the edge of the map, the unit may pause as it loads new

map data.

Using the Cursor

The cursor allows you to pan away from your present position and scroll to other map areas around

the world (even outside of your current detail coverage). As you pan past the edge of the current map

display, the screen will actively scroll forward to provide continuous map coverage. You will see an

hourglass symbol by the pointer while the unit is busy drawing new map detail.

To move the cursor:

1. Press the ARROW KEYPAD to move the cursor in an up, down, left or right direction.

As you move the cursor, the distance and bearing from your present position to the cursor will be

displayed in the data window, along with the cursor’s position coordinates. Keep in mind that when

the cursor is stationary, the distance and bearing from your present position will change as your boat

moves. The cursor may also be used to ‘snap’ to on-screen waypoints and map items, allowing you to

review a selected position directly from the map display.

To select an on-screen waypoint or map item with the cursor:

1. Use the ARROW KEYPAD to move the cursor to the desired waypoint or map item (if there are

several waypoints grouped closely together, zoom in closer for a better view).

2. When a waypoint or map item is selected, it will become highlighted on screen, with the name and

position displayed. Press ENTER/MARK to show details of the map item. When using BlueChart or

MapSource data, additional information tabs will appear. Use the ARROW KEYPAD to highlight

the individual tabs to display the information and additional options.

3. Press ENTER/MARK to conﬁ rm the new waypoint using the default three-digit name and symbol.

Selecting Map Scales

The map display has 28 available range scales from 20 ft. to 800 mi. (5 m to 1200 km). The

map scale is controlled by the IN and OUT keys, with the current scale displayed at the bottom

right of the data window.

To select a map scale:

1. Press the OUT key to zoom out and the IN key to zoom in.

The scale value represents the distance from one end of the scale bar to the other.

The GPSMAP 182/182C/232’s system has a built-in worldwide database to 20 mi, with more

detailed coverage available through the use of the optional BlueChart or MapSource data. The GPSMAP

182/182C/232 will display cartography as long as there is chart information available for the range

you’ve selected. Map coverage will conform to the following conditions:

• When the selected zoom range is covered by either the internal database, BlueChart, or MapSource

data, cartography will be displayed.

• When the selected zoom range is covered by both the internal database and BlueChart/MapSource

data, cartography will be displayed using the data with the best resolution.

• When the selected zoom range exceeds the resolution of the data in use, overzoom cartography will

be displayed and an ‘overzoom’ warning will appear below the scale ﬁ eld.

Compass Page

The GPSMAP 182/182C/232 features two different navigation pages: Compass and Highway.

Whenever a NAV, Follow Track (TracBack) or Follow Route have been activated, the GPSMAP

182/182C/232’s Compass Page will guide you to your destination with digital readouts and a graphic

compass display, which includes a bearing pointer. Use this page (instead of the Highway Page) when

travelling at slower speeds, when making frequent directional changes, or where straight-line naviga-

tion is not possible due to obstructions or terrain. The middle of the page features a rotating ‘compass

ring’ that shows your course over ground (track) while you’re moving. Your present course over ground

is indicated at the top of the compass ring. A bearing pointer arrow, in the middle of the compass ring,

and a bearing ‘bug’ indicator on the outside of the compass ring, indicate the direction of the destina-

tion (bearing) relative to the course over ground. The compass ring and pointer arrow work indepen-

dently to show—at a glance—the direction of your movement and the direction to your destination.

For instance, if the arrow points up, you are going directly to the waypoint. If the arrow points any

direction other than up, turn toward the arrow until it points up, then continue in that direction.

The bearing pointer, bearing bug and/or compass ring may point in various directions

when you are stationary or at very low speeds. Once you start moving, the pointer

will be correct.

The GPSMAP 182/182C/232’s Compass Page features a menu page that provides access to layout

and data ﬁ eld options. The data window, located at the top of the page, provides a user-selectable

layout of various types of useful data. Each data ﬁ eld may be conﬁ gured to display several data options.

The data window layout may also be changed to display more/less data ﬁ elds and change the actual

size of the data displayed.

Highway Page

Whenever a Go To, TracBack or route has been activated, the GPSMAP 182/182C/232’s Highway

Page will provide digital and graphic steering guidance to the destination with the Navigation Page.

The top half of the Highway Page features user-selectable data ﬁ elds that display useful navigation data.

Additionally, a compass ribbon is displayed to show your current heading along with a dark, vertical

bar which will indicate the bearing to your course. To stay on course, steer towards the dark, vertical

indicator (or arrows) until it lines up with the lighter red bar in the middle. The bottom section of

the screen provides visual guidance to the waypoint on a graphic highway display. The line down the

center of the highway represents your desired track line.

As you head toward your destination, the highway perspective moves to indicate your progress to

the waypoint and which direction you should steer to stay on course. If you are navigating a route, the

Highway Page shows each route waypoint in sequence connected by a red “road” with a yellow line

down the middle, which is your desired track line. Nearby waypoints not in the active route can also

be displayed. The highway perspective scale may also be zoomed in or out to display a larger or smaller

view of the highway. Five settings are available from 1X to 16X, with a default setting of 8X.

To change the highway perspective scale:

1. Press the IN or OUT key to select the desired setting.

Creating Waypoints

Creating and Using Waypoints

The Garmin GPSMAP 182/182C/232 stores up to 3000 alphanumeric waypoints with a user-

deﬁ ned icon, comments and depth available for each waypoint. Waypoints can be created using two

basic methods:

• ENTER/MARK key– used primarily for marking your present position, the ENTER/MARK key also

provides options that allow you to select a map position or map item from the map display. You may

also enter a new waypoint’s position coordinates manually (from a chart, etc.).

• Graphically– allows you to deﬁ ne a new waypoint position from the map display using the ARROW

KEYPAD.

ENTER/MARK Key

The Garmin GPSMAP 182/182C/232’s ENTER/MARK key lets you quickly capture your pres-

ent position— or cursor or map item position— in order to create a new waypoint. You must have a

valid position (2D or 3D) ﬁ x to mark your present position. This can be determined by looking at the

GPS Tab on the Main Menu. When you move the cursor over a map item, you will see a highlighted

description of that item. You may also use this option to manually enter waypoint coordinates.

To mark your present position:

1. Press and hold the ENTER/MARK key until the ‘New Waypoint’ window appears then release it.

You will see a default three-digit name and symbol for the new waypoint.

2. To accept the waypoint with the default name and symbol, press ENTER/MARK to conﬁ rm the

highlighted ‘OK’ prompt.

3. To enter a different name, highlight the name ﬁ eld and press the ENTER/MARK key, then use the

ARROW KEYPAD to enter the new letter/numbers and press ENTER/MARK when done. Note: You

may use up to 10 alphanumeric characters for the name.

4. To enter a different symbol, highlight the symbol ﬁ eld to the left of the name and press the ENTER/

MARK key, then use the ARROW KEYPAD to highlight the new symbol and press ENTER/MARK.

5. To enter optional comments or a depth, highlight the “Comments” or “Depth” ﬁ eld to the right

of the position coordinates and press the ENTER/MARK key, then use the ARROW KEYPAD to

enter a value and press ENTER/MARK.

6. To manually enter a set of coordinates, highlight the coordinates and press the ENTER/MARK

key, then use the ARROW KEYPAD to enter the new coordinates and press ENTER/MARK when

done.

7. When done, use the ARROW KEYPAD to highlight the ‘OK’ prompt and press ENTER/MARK to

save the waypoint into memory.

Creating Waypoints Graphically

Waypoints may also be quickly created from the map display, which allows you to ‘point and shoot’

at any map position to create a new waypoint. To mark a map item, select the desired map item with

the cursor. When selecting a map item, the option ‘Create Wpt’ will appear in addition to a description

of that point and its distance and bearing from your current position.

Going to a Destination

Using the NAV key, the GPSMAP 182/182C/232 provides three ways to navigate to a destination:

Go To Point, Follow Route and Follow Track (TracBack). Once you are actively navigating, you will see

a straight line that always runs from your current location to the destination. The easiest method for

selecting a destination is the ‘Go To’ function, which lets you select a destination point and quickly sets

a direct course from your present position. If you have a point highlighted on a list or the map, ‘Go To

<point name>’ will appear in addition to ‘Go To Point’. The ‘Go To’ function can be accessed from any list

of points or graphically from the map display.

To activate a ‘Go To’ from a point list:

1. Press the NAV key.

2. Use the ARROW KEYPAD to highlight ‘Go To Point’ and press ENTER/MARK.

3. From the ‘Find’ menu, highlight ‘Waypoints’ and press ENTER/MARK. (You may also choose to go to

other points, such as Cities, Tide Stations, etc. from this list.)

4. To select a waypoint from the waypoint lists, use the ARROW KEYPAD to highlight either the ‘User’

or ‘Nearest’ tab, select a waypoint and press ENTER/MARK. To select a waypoint from the map,

highlight either the ‘User’ or ‘Nearest’ tab and press MENU. With ‘Select From Map’ highlighted,

press ENTER/MARK. Use the zoom IN and OUT buttons and the ARROW KEYPAD to select a

waypoint, then press ENTER/MARK.

5. You may also activate a ‘Go To’ for any point, on any list. With any list point highlighted, press the

NAV key. You will see

‘Go To <point name>’ appear

, then press ENTER/MARK.

Selecting a ‘Go To’ Graphically

A graphical ‘Go To’ may be used to select one of three items from the map display: an existing

waypoint, an on-screen map item (roads, rivers, cities, navaids, etc.), or a new map point (non-map

item). If you are selecting a map item as the ‘Go To’ destination, the GPSMAP 182/182C/232 will auto-

matically use the name of the map item, but the point will not be stored in the waypoint list. See page

Choose a waypoint from

either the ‘User’ or ‘Near-

est’ tab list.

The waypoint or map

item name will auto-

matically appear when

highlighted and NAV is

pressed.

31 for creating waypoints using map items. If you are selecting a new map point (non-map item) as the

‘Go To’ destination, the GPSMAP 182/182C/232 will automatically create or move a waypoint named

‘MAP’ at the cursor position.

To activate an existing waypoint or map item as a ‘Go To’ from the map display:

1. Use the ARROW KEYPAD to highlight the waypoint or map item on screen and press NAV.

2. You will see ‘Go To <waypoint name>’, then press ENTER/MARK. You may also highlight the

waypoint or map item, press ENTER/MARK, highlight ‘Go To’ from options at the bottom of the

window and press ENTER/MARK.

To activate a new map point (non-map item) as a ‘Go To’ from the map display:

1. Use the ARROW KEYPAD to move the arrow cursor to the desired position.

2. Press NAV, you will see ‘Go To MAP Point’ highlighted, then press ENTER/MARK.

TracBack Navigation (Follow Track)

The second method of navigating to a destination is by using the TracBack or Follow Track feature.

The TracBack function allows you to retrace your path using the track log automatically stored in the

receiver’s memory, which will eliminate the need to store waypoints along the way. TracBack routes are

created by reducing your track log into a route of up to 50 turns and activating an inverted route along

those points. Once activated, a TracBack route will lead you back to the oldest stored track log point, so

it’s a good idea to clear the existing track log before you start your current trip.

To clear the track log and deﬁ ne a starting point for a TracBack route:

1. Press the MENU key twice to display the Main Menu page.

2. Using the ARROW KEYPAD, highlight the ‘Track’ tab, then highlight the ‘Active’ tab to the right.

3. Use the ARROW KEYPAD to select the ‘Erase’ option and press ENTER/MARK.

4. Highlight the ‘OK’ ﬁ eld and press ENTER/MARK.

You must ﬁ rst save the track log before you can use the ‘Follow Track’ feature. The Save feature

allows you to store up to 15 track logs from certain times and dates.

TracBack Navigation

To save a track log:

1. From the Main Menu, use the ARROW KEYPAD to highlight the ‘Track’ tab, then highlight the

‘Active’ tab to the right.

2. Use the ARROW KEYPAD to select the ‘Save’ option and press ENTER/MARK.

3. From the ‘Save Back Through’ window, highlight the desired time, date, or ‘Entire Log’ and press

ENTER/MARK.

4. Next, the track will begin saving and then display the ‘Saved Track’ window when done. The default

name, distance and number of points (500 max) will be displayed.

5. To change the name of the saved track, highlight the name ﬁ eld and press ENTER/MARK, make

your changes and press ENTER/MARK again. You may also choose a style (monochrome units) or

color (color models) that will be used to display the saved track line. If you wish for the saved track

to be displayed on the Map and Highway page, highlight the check box to the left of ‘Show on Map

and Highway’ and press ENTER/MARK. Highlight ‘OK’ and press ENTER/MARK to save the track.

To activate a TracBack using the NAV key:

1. Press the NAV key, then highlight the ‘Follow Track’ option and press ENTER/MARK.

2. Highlight the track you wish to follow and press ENTER/MARK.

3. Choose either ‘Original’, which will navigate you from the start to the end of your trip, or ‘Reverse’,

which will navigate you from the end to the start of your trip and press ENTER/MARK.

Once a TracBack has been activated, the GPSMAP 182/182C/232 will take the track log currently

stored in memory and divide it into segments called ‘legs’. Up to 50 (254 on 182C) temporary ‘turns’

(BEGIN, TURN 1, TURN 2, TURN 3,...., TURN X, END) will be created to mark the most signiﬁ cant

features of the track log in order to duplicate your exact path as closely as possible. To get the most out

of the TracBack feature, remember the following tips:

• Always clear the track log at the point that you want to go back to (dock, etc.).

• The ‘Record Mode’ option on the track log setup page must be set to ‘Fill’ or ‘Wrap’.

• There must be at least two track log points stored in memory to create a TracBack route.

TracBack Navigation/

MOB: Man OverBoard

• If the track log interval is set to the ‘Time’ option, the route may not follow your exact path (keep

the interval set to ‘resolution’ for best performance).

• If the receiver is turned off or satellite coverage is lost during your trip, the TracBack will draw a

straight line between any point where coverage was lost and where it resumed.

• If your track log’s changes in distance and direction are too complex, 50 waypoints may not mark

your path accurately. The receiver then assigns the 50 waypoints to the most signiﬁ cant points of

your track, and simpliﬁ es segments with fewer changes in direction.

To stop TracBack navigation:

1. Press the NAV key, highlight ‘Stop Navigation’ and press ENTER/MARK.

For more information on setting up the Track options and saved tracks, see pages 59-60.

2. Press the ENTER/MARK key to conﬁ rm and begin navigating to the MOB position.

Once a MOB has been activated, a ‘MOB’ waypoint with an international MOB symbol will be

created and the unit will be on an active navigation to that point. Use any of the Navigation Pages to

guide you back to the MOB point. The MOB waypoint will be stored in the waypoint list and may

be deleted like any other waypoint.

To stop navigation to the MOB position:

GPS Tab

GPS Tab— provides a visual reference of satellite acquisition, receiver status, and accuracy. The

status information will give you an idea of what the receiver is doing at any given moment. The sky

view and signal strength bars give you an indication of what satellites are visible to the receiver and

whether or not they are being tracked. The signal strength is shown on a bar graph for each satellite,

with the satellite number below. As the receiver locks onto satellites, a signal strength bar will appear

for each satellite in view. The progress of satellite acquisition is shown in three stages:

• No signal strength bars— the receiver is looking for the satellites indicated.

• Light signal strength bars— the receiver has found the satellite(s) and is collecting data.

• Dark signal strength bars— the receiver has collected the necessary data and the satellite(s) are ready

for use.

As soon as the GPSMAP 182/182C/232 has collected the necessary data from the best satellites in

view to calculate a ﬁ x, the status ﬁ eld will indicate a 2D or 3D status. The unit will then update the

position, date and time.

You can use the sky view to help determine if any satellites are being blocked, and whether you

have a current position ﬁ x (indicated by a ‘2D’,‘2D Differential’,‘3D’, or ‘3D Differential’ in the status

ﬁ eld). The sky view shows a bird’s-eye view of the position of each satellite relative to the receiver’s

last known position. The outer circle represents the horizon (north up), the inner circle 45º above the

horizon, and the center point a position directly overhead. You can also set the sky view to a ‘Track Up’

conﬁ guration, causing the top of the sky view to align along your current track heading.

WAAS Capability

The GPSMAP 182/182C/232 is capable of receiving WAAS (Wide Area Augmentation System) sat-

ellite signals. WAAS is an FAA (Federal Aviation Administration) funded project to improve the overall

accuracy and integrity of the GPS signal for aviation use, but land/sea based users may also beneﬁ t

from this system. At this time, the system is still in the development stage and is not fully operational.

There are currently two WAAS satellites that can be received in the U.S.A., one over the Atlantic Ocean

and one over the Paciﬁ c Ocean, in a geo-stationary orbit over the equator. Effective use of the WAAS

satellite signal may be limited by your geographic location in relation to those satellites, now in devel-

opmental service. WAAS satellite signal reception requires an absolute clear view of the sky and works

best when there are no nearby obstructions such as buildings, mountains, etc. WAAS satellites will be

numbered 33 or higher when viewing the sky view on your GPSMAP 182/182C/232. Initial reception

of the WAAS signal may take up to 15-20 minutes, then 1-2 minutes afterwards. When WAAS differen-

tial correction has been received for GPS satellites (numbers 32 or below), a ‘D’ will appear in the signal

bar of the sky view and ‘2D or 3D Differential’ will appear in the receiver status. To learn more about

the WAAS system, its satellite positions and current state of development, visit the FAA web site (http:

//gps.faa.gov). Since WAAS requires CPU resources of the GPSMAP 182/182C/232 to search for and

track the satellites, you may disable the WAAS feature to improve unit performance if WAAS reception

is not available in your area.

To Disable/Enable WAAS capability:

1. From the GPS Tab, press MENU, then use the ARROW KEYPAD to highlight ‘WAAS Off’ or ‘WAAS

On’ and press ENTER/MARK.

Receiver Status, Accuracy and DOP

Receiver status is indicated at the top ﬁ eld of the page, with the current Accuracy and Dilution Of

Precision (DOP) to the right of the sky view. DOP is an indication of satellite geometry quality measured

on a scale of one to ten (lowest numbers the best, highest numbers the poorest). Accuracy uses DOP

and other factors to calculate horizontal position accuracy in feet or meters. The status ﬁ eld will show

one of the following conditions:

• Looking For Satellites— the receiver is looking for any satellites.

• AutoLocate— the receiver is looking for any satellite whose almanac has been collected. This

process can take up to ﬁ ve minutes.

• Acquiring Satellites— the receiver is looking for and collecting data from satellites visible at its last

known or initialized position, but has not collected enough data to calculate a ﬁ x.

• 2D— at least three satellites with good geometry have been acquired and a 2 dimensional position

ﬁ x (latitude and longitude) is being calculated. ‘2D Differential’ will appear when you are receiving

DGPS corrections in 2D mode and a ‘D’ will show on the strength bar of satellites being corrected.

Highlight ‘WAAS Off’ and

press ENTER/MARK to

disable the WAAS

capabilities.

• 3D— at least four satellites with good geometry have been acquired and your position is now

being calculated in latitude, longitude and elevation. ‘3D Differential’ will appear when you are

receiving DGPS corrections in 3D mode and a ‘D’ will show on the strength bar of satellites being

corrected.

• Poor GPS Coverage— the receiver is no longer tracking enough satellites for a 2D or 3D ﬁ x.

• Receiver Not Usable— the receiver is unusable, possibly due to interference or abnormal satellite

conditions. Turn the unit off and back on to reset.

• Simulating— the receiver is in simulator mode.

The Differential Receiver status will show one of the following:

• Off— No optional beacon receiver attached or enabled in the Comm menu or WAAS Off

• Searching For WAAS— WAAS is enabled and receiver is searching for WAAS signal

• Using WAAS— WAAS capability enabled and unit receiving WAAS corrections

• No Beacon Signal— DGPS receiver attached, but not transmitting RTCM data to GPS

• Tuning Beacon— Receiver is tuning manual DGPS frequency

• Receiving Beacon— Unit is receiving DGPS corrections

• Scanning Beacon— DGPS receiver is scanning for available frequency

The Differential SNR (Signal to Noise Ratio) indicates, on a scale to 0-30db with 30db being the

best, the strength of the DGPS signal being received. If no optional DGPS receiver is used with the

GPSMAP 182/182C/232, the ‘DGPS Rcvr’ ﬁ eld will display ‘Off. The SNR will depend upon the mount-

ing of your DGPS receiver and the distance from the DGPS transmitting station.

Active Track Tab

Track Tab— lets you specify whether or not to record a track log (an electronic ‘breadcrumb trail’

recording of your path), deﬁ ne how it is recorded, or save track log data for future use. The Track

Logs Page also provides an indicator of the memory used for the active track log and options to clear

the track memory or start a TracBack route. See pages 38-40 for TracBack information. The Track

submenu is divided in two tabs: ‘Active’ tab and the ‘Saved’ tab.

The ‘Active’ tab is for the active log (the log currently being recorded). It displays track memory

used and current settings.

The ‘Saved’ tab displays and manages a list of any saved track logs, allows TracBack activation,

map display of saved logs. The active log stores up to approximately 2500 track log points, based upon

the criteria speciﬁ ed in the Track settings. Up to 15 track logs may be saved in memory, with up to 500

track log points in each saved log.

For the ‘Active’ tab, the following settings are available:

• Record Mode— lets you select one of three track recording options:

Off— No track log will be recorded. Note that selecting the ‘Off’ setting will prevent you from

using the TracBack feature.

Fill— a track log will be recorded until the track memory is full.

Wrap— A track log will be continuously recorded, wrapping through the available memory

(replacing the oldest track data with new data).

• Interval— deﬁ nes the frequency at which the track plot is recorded. Three interval settings are

available:

Distance— records track based on a user-deﬁ ned distance between points.

Time— records track plot based on a user-deﬁ ned time interval.

Loran TD

Loran TD System

LORAN C is a radio navigation aid operated and maintained in the United States by the United

States Coast Guard. The name LORAN is an acronym for “LOng RAnge Navigation”. The LORAN

system covers the entire United States and the U.S. Coastal Conﬂ uence Zone. From the perspective

of a mariner, the system is used for ocean and coastal navigation. It can be used as a supplemental

system for harbor and harbor approach navigation, and it is used for inland navigation by recreational

vehicles.

LORAN TD Feature

The LORAN TD (Time Delay) feature eases the transition from using LORAN to using GPS. The

GPSMAP unit automatically converts GPS coordinates to LORAN TDs for those who have a collection

of LORAN ﬁ xes for favorite ﬁ shing spots and other waypoints recorded as TDs. You can display your

position as a TD or enter waypoints as TDs. The accuracy to be expected from this conversion is

approximately thirty meters. When the unit is placed in the LORAN TD format mode, it simulates

the operation of a LORAN receiver. Position coordinates may be displayed as TDs, and all navigation

functions may be used as if the unit was actually receiving LORAN signals.

Using the LORAN TD Format

When creating new waypoints using LORAN TD coordinates, you must set the correct LORAN

chain number and secondary stations in the Setup TD ﬁ eld before storing the waypoint. You must have

the correct chain number as well as the secondary station identiﬁ ers to use this option correctly. These

values will vary per coordinate set or geographical location. Failure to enter correct information could

result in inaccuracies for the desired destionation. After the waypoint is stored in unit memory, it will

always reference the LORAN chain number and secondary stations currently selected in the Setup TD

ﬁ eld. If you enter a different LORAN chain number, change the secondary stations or offsets in the

Setup TD ﬁ eld, the active waypoint information will reﬂ ect those changes. Since the GPSMAP unit does

not rely on the LORAN signal for navigation, it can reference a different GRI chain and/or secondary

stations and still navigate to the location stored in memory.

You may change to Loran TD from the Units

Tab on the Main Menu.

182C Manual Part 2.indd 68 6/4/2003, 2:54:22 PM

Appendix A

Loran TD Setup

The LORAN Position Format ﬁ eld is located under the Units tab in the Main Menu. The ‘LORAN

TD Setup’ window contains the ﬁ elds to select the Loran GRI-Chain Number, Primary and Secondary

Stations, and TD Offsets.

To setup Loran TD from the Main Menu:

1. Using the ARROW KEYPAD, highlight the “Units” tab and then the “Position Format” ﬁ eld and

press ENTER/MARK. You may also press MENU from the “Units” tab to display the ‘Loran TD On’

option. (If you use ‘Loran TD On’, skip to step 3.)

2. Highlight ‘Loran TD’, press ENTER/MARK, then highlight ‘Setup’ and press ENTER/MARK.

3. To change the settings of any of the ﬁ ve ﬁ elds, highlight the ﬁ eld, press ENTER/MARK, select/enter

the desired setting and press ENTER/MARK.

4. When done, press the QUIT key to return to the Main Menu.

If the active GRI Chain, secondary stations or offsets have been changed since the waypoint was

created, the waypoint will now reference the active GRI-chain and secondary stations and adjust the

TD coordinates accordingly. Remember that the GPS is not relying on the LORAN signal for navigation

and actually converts the TD coordinate to a useful LAT/LON coordinate (in the background) before

storing the waypoint to memory or using it for navigation. Because of this the unit can navigate to a

TD coordinate anywhere in the world.

Handbook” from the Garmin web site at http://www.garmin.com/support/userManual.html.

WHAT IS DIGITAL SELECTIVE CALLING (DSC)?

Digital Selective Calling (DSC) uses marine VHF radio and Global Positioning System (GPS) tech-

nologies to transmit and receive location information. DSC is used by mariners to assist them in two

major areas: Distress Calls and Position Reporting.

An emergency DSC Distress Call allows a vessel in trouble to transmit a substantial amount of infor-

mation in a single transmission or “call,” without the need for voice communication. When any nearby

rescuer receives the DSC signal, an alarm sounds and they immediately receive the position of the caller.

The rescuer may then choose to navigate (Go To) the caller’s position to assist or forward the call on

to the Coast Guard. When the Coast Guard receives the call, they can immediately access the caller’s

information (such as who they are and the type of vessel) in their database while they are in transit to

the caller’s position.

A non-emergency DSC Position Report allows mariners to exchange and display the positions of one

another. Once a DSC position is received, the mariner may choose to create a waypoint or to show the

received position on an electronic map.

Anytime a vessel receives a DSC call, they can store that location and quickly navigate to that

position using a Go To. This makes DSC a time saver, especially in an emergency situation. In order to

use DSC, users must ﬁ rst register their VHF radio with the FCC and receive a Maritime Mobile Service

Identity (MMSI) number.

WHAT IS A MARITIME MOBILE SERVICE IDENTITY (MMSI)?

Maritime Mobile Service Identity (MMSI) basically allows a VHF radio to act like a phone. In order

to make a “call” on a phone, you ﬁ rst need a phone number to dial. The 9 digit MMSI number acts like

a phone number when used in a Position Report and as a unique identiﬁ er to the Coast Guard when

used in an emergency Distress Call. In order to to obtain a Maritime Mobile Service Identity (MMSI)

number, users must register their VHF radio with the FCC (Form 605). Garmin does not supply this

number! Information to obtain this number can be found on the next page.

Digital Selective Calling (DSC)

182C Manual Part 2.indd 70 6/4/2003, 2:54:23 PM

Appendix B

HOW ARE MMSI ASSIGNMENTS OBTAINED?

Non-commercial users (e.g. recreational users who remain in domestic waters and only carry VHF,

EPIRB (Emergency Position Indicating Radio Beacons), and Radar) are not required to have a FCC

ship station license. The FCC and Coast Guard have authorized some second and third party vendors

to assign MMSI numbers. This service is limited to registering recreational vessels only. To receive

information on how to obtain a recreational MMSI number please contact: http://www.uscg.mil/

rescue21/links/mmsi.htm or http://wireless.fcc.gov/marine/.

U.S Non-Federal User: Commercial users, or those who travel outside the U.S. or Canada, must

apply for a ship station license, or an amendment to a ship station license. To ﬁ nd out if you require

a Ship Station license contact: http://wireless.fcc.gov/marine/fctsht14.html. If your vessel requires

licensing by the FCC you will obtain a MMSI during the application/licensing process when you ﬁ le

FCC Forms 159 and 605.

U.S. Federal User: Federal users can obtain MMSI assignments from their agency radio spectrum

management ofﬁ ce. These procedures are currently under review by the NTIA (National Telecommuni-

cations and Information Administration).

Outside the U.S.: Users can obtain an MMSI assignment from their telecommunications authority

or ship registry, often by obtaining or amending their ship station license.

In Canada: Industry Canada is responsible for assigning MMSI numbers to commercial and

recreational vessels. Information is available at the following web site: http://apollo.ic.gc.ca/english/

mmsi.html.

For more information regarding MMSI’s visit: http://www.navcen.uscg.gov/marcomms/gmdss/

mmsi.htm.

HOW CAN GARMIN HELP YOU WITH DSC?

To receive Distress Calls or Position Reports, the user must have a DSC-equipped chartplotter as well

as a VHF radio with DSC support. During normal, non-emergency Position Report communication,

Channel 70 (156.525 MHz) has been set aside as the VHF/DSC digital call channel. For a Distress Call,

a mariner presses the MayDay button on their VHF radio. The call transmits on an emergency channel

Digital Selective Calling (DSC)

182C Manual Part 2.indd 71 6/4/2003, 2:54:23 PM

Digital Selective Calling (DSC)

Appendix B

with the MMSI number attached to the call (if the user has DSC support). Any DSC-equipped mariner

(on sea or land) within range can receive the call.

When the Garmin GPSMAP 182/182C/232 is connected to a VHF with DSC support, the GPS unit

displays a Call List, Log, and a Directory available to store incoming information received from another

user’s DSC capable VHF/GPS combination. Basic wiring is required for the Garmin unit and VHF radio

to send and receive NMEA data from each other (pg.87).

Distress Call

With a Garmin DSC capable chartplotter/sounder properly connected to a VHF radio with DSC

output, the user may receive any DSC Distress Call within range. A window will pop up and a message

will display when a Distress Call is received. To notify the user a Distress Call has been received, an

alarm will sound (if enabled). The alarm only

sounds on a Distress Call, and it will not sound on a

Position Report. Distress Calls are broadcasted to all DSC users in radio range.

Options available from this screen are:

• Show on Map: If the user immediately wants to see the caller’s position they select ‘Show on

Map’.

• Create Waypoint: If the user wanted to create a waypoint of that posistion they highlight

‘Create Waypoint’ and press ENTER/MARK.

The user also has the ability to input the user’s name, if it is known. (NOTE: The user’s name

replaces the MMSI number as a reference once it is entered.)

DSC Position Report

The Position Report operates similarly to the Distress Call. Remember this type of contact is like a

phone call, but no emergency alarms are set off and the call is speciﬁ c to the receiver. Position Reports

are not broadcasted to all DSC users.

ers who have more than one GPS chartplotter. If the user wants only DSC to display on a particular

chartplotter, turn DSC off on the remaining Garmin chartplotters that support DSC.

A user also has the ability to simulate a Distress Call or a Position Report on this page. This is help-

Time Offsets

The chart below gives an approximate UTC (Universal Time Coordinate) time offset for the various

longitudinal zones. Check with local charts for more detailed information. If you are in daylight savings

time, add one hour to the offset.

A simple way to determine your local time offset is how

many hours you are behind or ahead of UTC (also called

‘Greenwich’ or ‘zulu’ time).

Example: EST (Eastern Standard Time) is 5 hours behind

UTC, so your offset would be -5. Adding one hour for

daylight savings would make EDT (Eastern Daylight Time)

- 4. Subtract an hour for each time zone as you travel

west.

Offsets for Continental U.S. would be:

EST -5 EDT -4

CST -6 CDT -5

MST -7 MDT -6

PST -8 PDT -7

Speciﬁ cations

Cleaning - The GPSMAP 182C lens is coated with a

special anti-reﬂ ective coating which is very sensitive to skin

oils, waxes and abrasive cleaners. CLEANERS CONTAIN-

ING AMMONIA WILL HARM THE ANTI-REFLECTIVE

COATING. It is very important to clean the lens using an

eyeglass lens cleaner which is speciﬁ ed as safe for anti-

reﬂ ective coatings and a clean, lint-free cloth. Units with a

monochrome display may use the same cleaning method.

The unit’s case is constructed of high quality material and

does not require user maintenance other than cleaning.

Clean the unit housing using a cloth lightly dampened with

a mild detergent solution and then wipe dry. Avoid chemical

cleaners and solvents that may damage plastic components.

Do not apply cleaner to electrical contacts on the back of

the unit.

Storage - Do not store the unit where exposure to tempera-

ture extremes may occur (see left), as permanent damage

may result. User information, such as waypoints, routes,

etc. will be retained in the unit’s memory, without the need

for external power. It is always a good practice to back up

important user data by manually recording it or download-

ing it to a PC (see pg. 64).

Antenna Installation

Installing the GPSMAP 182/182C/232

The GPSMAP 182/182C/232 must be properly installed according to the following instructions to

get the best possible performance. If you have the GPSMAP 182/182C/232 with the built-in internal

bail mount antenna, you may skip this section and proceed to the next page. For unit’s purchased with

the remote GA 29 antenna, follow the instructions below. To complete the installation, you’ll need the

appropriate fasteners and a 1” x 14-thread marine antenna mount available at most marine dealers.

When in doubt, seek professional assistance.

Mounting the GPS Antenna

The antenna should be mounted in a location that has a clear, unobstructed view of the sky in all

directions to ensure the best reception. Avoid mounting the antenna where it will be shaded by the

boat’s superstructure, a radome antenna, or mast. Sailboat users should avoid mounting the antenna

high on the mast to prevent inaccurate speed readings caused by excessive heeling. Most marine

VHF and LORAN antennas should not seriously degrade the GPS antenna’s reception. Never paint the

antenna or clean it with harsh solvents.

The Garmin antenna screws directly onto any standard 1” x 14-thread antenna mount. If you

need to raise the antenna to avoid shading, try using a 1” x 14-thread extension mast available at most

marine dealers.

To install the GPS antenna:

1. Screw the antenna directly onto the 1” x 14-thread mount.

2. Route the cable to the mounting location of the display unit. Use the appropriate tie-wraps,

fasteners and sealant to secure the cable along the route and through any bulkhead or deck.

3. Once the GPSMAP 182/182C/232 unit has been installed, connect the cable to the antenna con-

nector on the back of the display unit. Make sure that you turn the antenna cable connector 1/4

turn clockwise to lock the cable into place.

It is possible to route the coaxial cable either through, or

outside the antenna mount. It is possible to remove the

BNC connector on the coaxial cable and the coaxial cable

shortened to ease installation, however, doing so will void the

antenna warranty. If the BNC connector is removed it must

be replaced with a new solder-on or crimp BNC connector.

Suggested locations for mounting the GA 29 antenna.

Unit Installation

Mounting the GPSMAP 182/182C/232 Unit

The GPSMAP 182/182C/232’s compact, waterproof case is suitable for mounting in exposed

locations or at the nav station. The unit comes with a gimbal bracket that can be used for surface or

overhead mounting. When choosing a location for the display unit, make sure you consider the follow-

ing conditions:

• There should be at least a 3” (7 cm) clearance behind the case to allow connection of the

antenna (external antenna only), power/data cables.

• The mounting surface should be heavy enough to support the unit and protect it from excessive

vibration and shock.

• For GPSMAP 182/182C/232 unit’s with the built-in internal bail mount antenna, it should be

mounted in a location that has the clearest, most unobstructed view of the sky in all directions to

ensure the best reception. Avoid mounting the unit where it will be blocked by the boat’s superstruc-

ture, a radar arch, or mast.

The temperature range for the GPSMAP 182/182C/232 is 5°F to 158°F (-15°C to 70°C).

Extended exposure to temperatures exceeding this range (in storage or operating

conditions) may cause failure of the LCD screen. This type of failure and related conse-

quences are NOT covered by the manufacturer’s limited warranty.

To install the GPSMAP 182/182C/232 unit:

1. Place the mounting bracket in the desired location.

2. Mark and drill the four mounting holes for the fastener you are using.

3. Fasten the bracket to the surface using the appropriate fastener.

4. Insert the GPSMAP 182/182C/232 into the mounting bracket. The bracket is designed for a tight ﬁ t

to provide additional support when swiveling the unit.

5. Screw the two mounting knobs through the bracket and into the display case.

6. Connect the power/data and antenna cables (external antenna only) to the back of the unit, making

sure the locking rings are fully tightened on both connectors.

182C Manual Part 2.indd 85 6/4/2003, 2:54:31 PM

Appendix H

Unit Installation

The GPSMAP 182/182C/232 with external antenna can be ﬂ ush mounted on a ﬂ at panel of .08-

.52” thickness using the cam lobe feature on its gimbal mounting bracket. When ﬂ ush mounting the

GPSMAP 182/182C/232, be sure to choose an appropriately sized location for the unit (see unit dimen-

sions pg. 83) and leave 1.25” (32mm) clearance below the data card slot for inserting/removing data

cards. For ﬂ ush mounting the GPSMAP 232 unit, skip to the next set of instructions.

To ﬂ ush mount the GPSMAP 182/182C unit using the gimbal mounting bracket:

1. Cut a 4.33”W x 4.33”H (110 x 110 mm) hole in the panel.

2. Place the GPSMAP 182/182C/232 into the hole from the front until the ﬂ ange rests against the

mounting surface.

3. From the back of the panel, loosely attach the bracket such that the slot in the ratchet area points

away from the mounting panel (ﬁ gure 1).

4. Rotate the bracket downward until the panel is pinched tightly between the unit’s ﬂ ange and

bracket lobe (ﬁ gure 1).

5. Tighten the knobs and connect the power/data and antenna cables. Note: if the panel is too thick

to allow use of the supplied knobs, two M6 screws may be used to secure the bracket.

The GPSMAP 182/182C/232, with external antenna, may also be ﬂ ush mounted on a ﬂ at panel

using its existing mounting bracket.

To ﬂ ush mount the GPSMAP 182/182C/232 unit:

1. Remove the four M5 screws from the back of the unit and remove the mounting bracket.

2. Using the mounting bracket as a template, outline the center relief area and mark the location of

the four screw holes centers on your bulkhead or other surface (ﬁ gure 2).

3. Cut the relief hole from the panel and drill the four 0.20” (5.08 mm) screw holes.

4. Place the GPSMAP 182/182C/232 into the relief hole until it rests ﬂ ush against the mounting

surface.

5. Secure the unit to the mounting surface using the M5 screws. Do not try to force the screws deeper

into the holes than the holes will allow. For thick mounting surfaces, insert the M5 screws directly

thru the drilled holes (ﬁ gure 3). For thin panels, place the mounting bracket on the back side of the

panel for more support. Connect the power/data and antenna cables.

Installing and Removing

Data Cards

Installing and Removing Data Cards

The GPSMAP 182/182C/232 uses optional Garmin marine BlueChart and MapSource data cards to

display digital charts and maps on-screen. Data cards are installed in the card slot located at the bottom

right of the unit. Data cards may be installed or removed at any time, whether the unit is on or off.

To install a data card:

1. Open the card door by pressing together on the two handles at the bottom of the door and

lifting it up and open.

2. Insert the card, with the label facing front and the handle bottom, into the slot.

3. Firmly push the card into the unit. It in not necessary to force the card and about 1/2” will still

be exposed when it is properly inserted. If the unit is on, a conﬁ rmation tone will sound and

a message will display on the screen noting the card details when the card has been properly

installed and accepted.

4. Close the cover.

If you insert a data card and get a ‘card format not recognized’ message, try removing the card and

reinserting it. If the card is still not recognized, contact Garmin Support or your Garmin dealer for

assistance. Data cards are not waterproof, should not be exposed to moisture or excessive static charges,

and should be stored in the case supplied with the card.

To remove a data card:

1. Open the card door by pressing together on the two handles at the bottom of the door and

lifting it up and open.

2. Grasp the card handle at the bottom and pull down ﬁ rmly.

3. If the unit is on, a conﬁ rmation tone will sound when the data card has been removed.

The ﬁ rst time you insert a

data card, the unit will take a

few seconds to read the card.

Appendix H

Installing Ferrite Clamp

Installing the Ferrite Bead Clamp (GPSMAP 182C Only)

In order to ﬁ lter Radio Frequency Interference (RFI) radiation, which could possibly interfere with

items such as televisions, radios, or other marine electronics that are operating in close proximity to

the GPSMAP182C with GA 29 remote antenna, a ferrite bead ﬁ lter clamp and neoprene foam strip are

included for attachment to the unit’s antenna cable. The clamp attaches to the antenna cable near the point

at which it connects to the back of the GPSMAP 182C. The foam strip has adhesive on one side and is

used to keep the clamp stationary on the cable.

To install the ferrite bead clamp:

1. Choose a location which is no more than two inches (5 cm) from the back of the GPSMAP 182C.

2. Remove the backing from the adhesive foam strip. Place the strip at an angle to the cable with

adhesive facing towards the cable. Snugly spiral wrap the foam strip around the antenna cable. (Fig. 1)

3. Open the ﬁ lter clamp by slightly pulling on the latch and opening the ﬁ lter halves.

4. Position the clamp (Fig. 2) and squeeze it shut around the cable until the latch is securely fastened. If

the clamp is difﬁ cult to close, you may want to remove some of the foam strip.

The clamp should not need to be replaced under normal use. Please contact your Garmin dealer or

Garmin Support if you have any questions or require a replacement ﬁ lter clamp.
