Dynamic route guidance

Route guidance from an off-map loca-
tion to a destination
If the vehicle position is outside the area cov-
ered by the digital map, then the vehicle is in
an off-map location. COMAND is also able to
guide you to a destination even from an off-
map location.
At the start of the route guidance, you will see
Off road
the message, an arrow and the dis-
tance to the destination. The arrow shows the
compass heading to the road left last.
The route is highlighted blue from the nearest
road known to the system.
As soon as the vehicle is back on a road
known to the system, route guidance contin-
ues in the usual way.
Off-road during route guidance
Due to roadworks, for example, there may be
differences between the data on the digital
map and the actual course of the road.
In such cases, the system will temporarily be
unable to locate the vehicle position on the
digital map and thus considers the vehicle to
be in an off-road position.
In the display, you will see the
sage, an arrow and the distance to the desti-
nation. The arrow shows the compass head-
ing to the last road you were driving on.
As soon as the system can assign the vehicle
position to the map again, route guidance
continues in the usual way.
Dynamic route guidance
Introduction
An RDS-TMC radio station transmits RDS-
TMC traffic reports in addition to the radio
programme. COMAND can receive the RDS-
TMC traffic reports and take them into con-
sideration for dynamic (traffic-dependent)
route guidance. The navigation system can,
for example, guide you around a traffic jam.
6 RDS-TMC is not available in all countries.
In Germany, COMAND uses the high-quality
traffic data from T-systems Traffic for the
TMCPro traffic jam warning system. In con-
trast to the public TMC service, TMCPro uses
exclusive traffic data that is detected with an
automated sensor network, in addition to the
messages generated by the TMC service. The
traffic data received from the traffic jam warn-
ing services named above could differ.
There may also be differences between the
traffic reports received and the actual road
and traffic conditions.
The respective traffic data being received
appears at the bottom right of the display with
the symbols "TMCPro" or "TMC". If there is no
reception, no symbol is displayed.
