4 - 2 Navigation
The system will also work with poor
GPS reception, however, the
accuracy of the determination of the
position will be reduced, resulting in
incorrect position messages.
After the entry of the destination
address or points 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 or a combination of two
displays.
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 such that traffic problems
related to pre-selected criteria 3 4-24
are avoided.
If there is a traffic problem during
active route guidance, depending on
the pre-setting 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 related
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 3 4-17.
Important information about
the map material on the DVD
The complete map material is too
extensive to load it into the system’s
memory.
For international navigation, insert
navigation 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 in the system memory.
Once the preferred map material has
been loaded, the DVD can be
removed so that the drive can be
used for playing music.
Map data add / remove
3 4-24.
