What is dynamic route guid-
ance?
Dynamic route guidance calculates the
route, while taking into account current
traffic announcements.
Traffic announcements are transmitted by
radio stations via the TMC (Traffic Mes-
sage Channel) in addition to the radio
programme and are received and analysed
by the navigation system. Receiving traffic
announcements is free of charge.
A continuous check is made for the pres-
ence of relevant messages for the selected
route. However, traffic problems are also
shown on the map even if route guidance
is deactivated.
If these continuous checks determine that
a traffic announcement is relevant to route
guidance, the unit will automatically re-
calculate a new route to the destination.
Displaying TMC messages on
the map
Current TMC messages are displayed on
the map graphically. Sections of the route
where there are traffic problems are high-
lighted blue. Arrows indicating the traffic
direction which is affected by the traffic
problem continue to be displayed.
In addition to the coloured mark, a warn-
ing sign is displayed on the stretch of road
affected.
Note:
Dynamic route guidance is not available
for all countries (currently only Belgium,
Germany, Denmark, France, Italy, The
Netherlands, Austria, Sweden, Switzer-
land and Spain).
TMC reception must be available in or-
der to activate dynamic navigation and
the functions described below.
Note:
As the traffic announcements are trans-
mitted by radio stations, we cannot as-
sume responsibility for the completeness
or accuracy of the announcements.
