Navigation
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.
The route guidance is provided by
voice output and an arrow, as well as
with the aid of a multi-colour map
display.
TMC traffic information system
and dynamic route guidance
The TMC traffic information system
receives all current traffic information
from TMC radio stations. If dynamic
route guidance is active, this
information is included in the
calculation of the overall route. During
this process, the route is planned so
that traffic problems related to pre-
selected criteria are avoided.
If there is a traffic problem during
active route guidance, depending on
the pre-settings, a message appears
as to whether the route should be
changed.
TMC traffic information is displayed in
the route guidance display as
symbols or as detailed text on the
TMC messages menu.
To be able to use TMC traffic
information, the system has to receive
TMC stations in the relevant region.
Dynamic route guidance only works if
traffic information is received via the
TMC traffic information system.
The dynamic route guidance function
can be deactivated

Map material
The complete map material is too
extensive to be loaded into the
system’s memory.
For international navigation, insert the
navigation CD/DVD or load the
related data for the regions into the
system memory. The network of main
roads in Europe is loaded
automatically. It may be necessary to
delete other map material from the
system memory.
Once the preferred map material has
been loaded, the CD/DVD can be
removed so that the drive can be used
for playing music.

An expensive replacement of the
device will then be necessary.
