Dynamic route guidance with TMC use
Requirements for a dynamic route guidance
TMC (Traffic Message Channel) is a digital radio data service for continuous trans-
mission of traffic information.
If a TMC traffic radio station is available for current location, the TMC traffic re-
ports are updated continuously in the background.
The quality of the transmitted traffic reports depends on the traffic editing car-
ried out by the radio station. The reception of the TMC traffic reports cannot be
switched on or off.
The station you are listening to does not have to be a TMC station.
TMC traffic reports can only be evaluated and displayed by the unit if the naviga-
tion data for the currently driven area is stored in the unit's memory or can be re-
trieved from an inserted navigation DVD.
The current TMC traffic reports can be displayed by pressing the range selector
key TMC .
Switching the dynamic navigation on or off › In the main menu

› Confirm the settings with the function key
OK .
Traffic problems received via TMC which affect the route are displayed in the map
by means of a coloured symbol. Traffic problems, which do not affect the route,
are displayed in the map by means of a grey symbol. The direction in which a traf-
fic problem is found, is displayed by means of an arrow in the symbol. The dura-
tion of a traffic problem on the route is displayed in the map by means of continu-
ous PKW (motor car) symbols .
Off You are not alerted to received traffic disruptions along your route and are guided
through the traffic disruption by the radio navigation system. TMC traffic reports
are however still updated automatically in the unit. They can be displayed by
pressing the range selector key TMC .
If one of the announced traffic disruptions lies along your route, you can also
switch on the dynamic route guidance during the current route guidance or block
the route manually . Manual During route guidance you can choose whether you want to divert around the re-
ported traffic problems along your route.
If the radio navigation system is alerted of a traffic disruption on the calculated
route, the driver will be notified of this by means of an audible message and infor-
mation in a pop-up window.
The expected delay incurred in avoiding this traffic problem and the length of the
alternative route will be displayed. The expected time lost when driving through
this traffic problem will also be displayed.
› Press the function key
Current tour to remain on the calculated route and to pass
through the traffic disruption.
› Press the function key
Bypass for an alternative route to be calculated taking in-
to account the announced traffic disruption.
Automatic You will be automatically diverted around the received traffic problems along your
route during route guidance.
After input of relevant traffic information for your route you will be advised of the
change in the current route guidance by means of an acoustic message. You will
automatically be guided around announced traffic jams or blocked roads, if this
saves time.
Such announcements will also take place if there was a traffic disruption on the
original route, which no longer exists and the radio navigation system recognises
the opportunity to drive the actually more advantageous route. Note
■ There may not be any advantage in avoiding the traffic jam if, as a result of the
TMC traffic reports, the diversion is also heavily congested. ■ If a traffic disruption was not yet entered via the TMC traffic reports, route
blocks can also be entered manually . Ð36
