Notes on GPS reception
The correct function of the navigation system
depends amongst other things on GPS recep‐
tion. In certain situations GPS reception can be
impaired, defective or even not possible, e.g. in
tunnels or in parking garages.
Changing direction overview
There are three phases when changing direction:
R
Preparation phase
If there is enough time between the changes
of direction, the multimedia system prepares
you for the upcoming change of direction. A
navigation announcement is issued, e.g.
"Prepare to turn right".
The map appears in full-screen mode.
R
Announcement phase
The multimedia system announces the
upcoming change of direction, e.g. by
announcing "Turn right in 300 ft (100 m)".
The display is split into two parts. The map is
displayed on the left; on the right, there is a
detailed image of the intersection or a 3D
image of the upcoming change of direction.
R
Change-of-direction phase
The multimedia system announces the immi‐
nent change of direction, e.g. by announcing
"Now turn right".
The display is split into two parts.
The vehicle has successfully changed direc‐
tion when the light-color bar on the right
drops down to 0 feet (0 m) and the current
vehicle position symbol has reached the
highlighted change-of-direction point.
When the change of direction is complete,
the map appears in full-screen mode.

Changes of direction are also shown in the
Instrument Display.
Lane recommendations overview
This display appears for multi-lane roads.
If the digital map contains the relevant data, the
multimedia system can display lane recommen‐
dations for the next two changes of direction.
