Main unit
The main unit is fitted in and behind the cen-
tre console and includes the following func-
tions:
•
Calculating the position of the car
(p. 30)
•
Calculating the route to the specified des-
tination (p. 41)
•
Handling traffic information (p. 73)
•
Voice guidance (p. 32)
Receiver for GPS and traffic information
1
(TMC ) is integrated into the main unit.
Positioning
The car's speed sensor and a gyro calculate
the current position and the direction of travel
of the car using signals from the GPS satellite
system.
The advantage of this concept is that the
Navigation system registers and calculates
the route outline even if the GPS signal is
temporarily lost, e.g. when driving through a
tunnel.
Traffic information

TMC is a standardised coding system for
traffic information. The receiver automatically
Traffic Message Channel

searches for the correct frequency. Reception
takes place via the FM antenna.
NOTE
TMC is not available in all areas/countries.
The system's coverage area is under con-
stant construction and updating may
sometimes be necessary.
Screen
The screen displays maps and provides
detailed information on route type, distance,
menus, etc.
Screen care
Clean the screen with a soft, lint-free rag,
lightly moistened with a mild window cleaning
agent.
IMPORTANT
Do not place any objects in front of the
GPS navigator's display screen - the sur-
face could then be scratched. Mobile
phones can also interfere with the display
screen's function.

As an alternative to the steering wheel key-
pad, the centre console's numerical keypad
can be used in combination with buttons OK/
MENU, TUNE and EXIT to scroll between dif-
