Navigation
Introduction
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).
Important information on
the function of the
navigation system
The position and movement of the
vehicle are detected by the
navigation system using sensors.
The distance travelled is determined
from the vehicle’s speedometer
signal, turning movements on bends
by a gyro sensor. The position is
determined using the GPS satellites
(Global Positioning System).
By comparing the sensor signals
with the digital maps on the
navigation DVD, it is possible to
determine the position with an
accuracy of approx. 10 m.

Caution
The usage of the navigation system
does not release the driver from the
responsibility for a correct, vigilant
attitude in road traffic. The related
traffic regulations must always be
followed. If a navigation instruction
should contradict traffic regulations,
the traffic regulations always apply.
