TMC traffic reports are used to optimise the route during route guidance when
there are traffic disruptions.
If a TMC traffic radio station is available for current location, the TMC traffic re-
ports are updated continuously in the background. The radio station currently be-
ing played does not affect the reception of traffic announcements.
The reception of TMC traffic reports is always switched on and cannot be turned
off.
The accuracy of the dynamic route guidance depends on the transmitted traffic
reports. The radio stations broadcasting this information are responsible for the
content.
TMC traffic reports can only be evaluated and saved by the radio navigation sys-
tem when navigation data are available for the driven area.

When the
Dynamic route
» page 44 function is switched on, the traffic reports influ-
ence the dynamic route guidance by means of TMC messages.
Making a diversion from a traffic jam based on TMC traffic reports may not always
offer a time advantage, e.g. if the diversion route is also congested.
If the route guidance is continued in spite of a traffic problem, the unit might
have calculated that a diversion would have taken more time than driving
through the location with the traffic problem.
Dynamic route switched on
Information on traffic problems received via TMC which affect the route are dis-
played in the map by means of a coloured symbol (e.g., , , , etc.) along with
the route section.
Route sections that lie along the route are displayed in red. Route sections along
the route that are modified due to traffic reports are displayed in orange. Traffic
problems which do not affect the route are displayed by means of a gray symbol.
Dynamic route switched off
You will not be alerted to received traffic disruptions along your route and are
guided through the traffic disruption by the radio navigation system. The traffic
reports are updated automatically in the unit and displayed by pressing the but-
ton
TRAFFIC
.
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 » page 58.
