Guidance ..................................... 53General information
The navigation system will reliably guide you to your destination.
The current traffic situation is taken
into account in the route calculation.
For this purpose, the Infotainment
system receives traffic
announcements in the current
reception area via RDS-TMC.
The navigation system cannot,
however, take into account traffic
incidents, traffic regulations changed
at short notice and hazards or
problems that arise suddenly (e.g.
road works).Caution
The usage of the navigation
system does not release the driver
from the responsibility for a
correct, vigilant attitude in road
traffic. The relevant traffic
regulations must always be
followed. If a navigation instruction contradicts traffic regulations, the
traffic regulations always apply.
Functioning of the navigation
system
The position and movement of the
vehicle are detected by the navigation
system using sensors. The travelled
distance is determined by the
vehicle’s speedometer signal, turning
movements on bends by a gyro
sensor. The position is determined by the GPS (Global Positioning System)
satellites.
By comparing the sensor signals with the digital maps, it is possible to
determine the position with an
accuracy of approx. 10 metres.
The system will also work with poor
GPS reception. However, the
accuracy of the determination of the
position will be reduced.
After the entry of the destination
address or point of interest (nearest
petrol station, hotel, etc.), the route is
calculated from the current location to the destination selected.
Route guidance is provided by voice
output and an arrow, as well as with
the aid of a multi-colour map display.
