General information
The navigation system will reliably
guide you to your destination. There
will be no need to read maps, even if
you have no local knowledge
whatsoever.
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 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 metres.
The system will also work with poor
GPS reception. However, the
accuracy of the determination of the
position will be reduced.
