The cross track error range is shown on the compass rose as a wide, white,
corridor enclosing the course line. The outer edges of this white corridor
represent lines that show the current cross track error range. The default
for the cross track error range is 0.20 miles.
For example, if the present position symbol touches the right cross track
error line, then you are 0.20 miles to the right of the desired course. You
need to steer left to return to the desired course. You can use the
ZIN or
ZOUT keys to change the cross track error range.
A circular symbol depicting your destination (waypoint) appears on the
screen as you approach the waypoint.
Trip Time is the time that it will take to reach your destination at your
present closing speed. You can also customize the time window to show
Arrival Time instead. Arrival Time is the local time it will be when you
arrive at the destination, based upon your present closing speed and track.
The Navigation Page has its own menu, which is used for some advanced
functions and for setting various options (Options and setup are discussed
in Sec. 8.). To access the Navigation Page Menu, from the Navigation
Page, press
MENU.
Map Page
The Map Page screens show your course and track from a "bird's-eye" view.
By default, this unit shows the map with north always at the top of the screen
(This can be changed. See the topic Map Orientation, in Sec. 8.). If you're
navigating to a waypoint, the map also shows your starting location, present
position, course line and destination. You, however, don't have to navigate to a
waypoint to use the map.
Map Page is the default screen that appears when you turn on the unit. To
get to the Map Page from another page: Press
PAGES| → or ← to MAP|EXIT.
When the Map Page is displayed, a screen similar to the following figure
appears.
The arrow in the center of the screen is your present position. It points in the
direction you're traveling. The map zoom range is the distance across the
screen. This number shows in the lower right corner. In the example below,
the range is 15 miles from the left edge of the map to the right edge of the
map.
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its
coverage area and the amount of mapping detail shown. There are 37
available map zoom ranges, from 0.05 miles to 4,000 miles.
