General information
The navigation system will reliably
guide you to your destination without
the need to read maps, even if you
have no local knowledge whatsoever.
The current traffic situation is taken
into account in the route calculation,
if dynamic route guidance is used. 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 satellites (Global Positioning
System).
By comparing the sensor signals with
the digital maps on the map SD card,
it is possible to determine the position
with an accuracy of approx. 10 m.
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.
