unknown message, an arrow and the distance
to the destination. The direction arrow shows

Dynamic route guidance
Introduction
Traffic reports via TMC
An RDS-TMC radio station transmits RDS-
TMC traffic reports in addition to the radio
programme. COMAND Online can receive
RDS-TMC traffic reports and take them into
consideration for dynamic (traffic-depend-
ent) route guidance. The navigation system
can, for example, guide you around a traffic
jam.
In Germany, COMAND Online uses high-qual-
ity traffic data for the TMCpro traffic jam
warning system. In contrast to the public TMC
service, TMCPro uses exclusive traffic data
that is detected with an automated sensor
network, in addition to the messages gener-
ated by the TMC service. The traffic data
received from the traffic jam warning 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.

RDS-TMC is not available in all countries.
Switching dynamic route guidance
on/off
If Dynamic route or Eco route is selected
as the route type, RDS-TMC traffic reports are
taken into account for route guidance.
The Fast route and Short route route
types do not take RDS-TMC traffic reports
into account for route guidance.
Selecting route type (Y page 64).

COMAND Online calculates a new route if
you change the route type setting with
route guidance active. If you change the
route type setting when route guidance is
inactive, COMAND Online uses the new
setting for the next route guidance.
