What is dynamic route
guidance?
Dynamic route guidance calculates the
route, while taking into account current
traffic announcements.
Traffic announcements are transmitted
by radio stations via the TMC (Traffic
Message Channel) in addition to the
radio programme and are received and
analysed by the navigation system.
Receiving traffic announcements is free
of charge.
If dynamic route guidance is active, a
continuous check is made for the
presence of relevant announcements for
the selected route (however, traffic
problems still appear on the map even
when route guidance is not active).
If these continuous checks determine
that a traffic announcement is relevant to
route guidance, the unit will
automatically recalculate a new route to
the destination (See “The TMC button”
on page 55.).
Displaying TMC messages on
the map
Current TMC messages are displayed on
the map in graphic form. Sections of the
route where there are problems with
traffic are highlighted green. A black
arrow also indicates the direction of
travel. In addition to the coloured mark,
a warning sign is displayed on the
stretch of road affected.
Note:
Dynamic route guidance is not availab-
le for all countries (currently only Bel-
gium, Germany, Denmark, France, Ita-
ly, The Netherlands, Austria, Sweden,
Switzerland and Spain).
TMC reception must be available in or-
der to activate dynamic navigation and
the functions described below. TMC re-
ception is only available when the unit
holder with TMC receiver is used.
Note:
As the traffic announcements are trans-
mitted by radio stations, we cannot as-
sume responsibility for the complete-
ness or accuracy of the announcements.
