road closures or a traffic jam caused by an accident. Both functions are subject to data
availability.
4.1.7.1 Historical traffic
If statistical traffic information is stored with the map data, the software can take them into
account when planning a route. In normal cases, these statistics help you avoid usual traffic
jams on the given day of week in the given hour but in some cases like on public holidays that
fall on normal weekdays, they can be misleading. You can enable this feature in Traffic
settings.
4.1.7.2 Real-time traffic information (TMC)
TMC (Traffic Message Channel) can provide you with the real-time status of the traffic. Route
calculation can avoid road blocks or unexpected traffic jams caused by an accident.
TMC is a specific application of the FM Radio Data System (RDS) used for broadcasting real-
time traffic and weather information.
Using traffic information is enabled by default in the software.
Note!
TMC is not a global service. It may not be available in your country or region.
Ask your local dealer for coverage details.
Your device contains the TMC receiver that is needed to receive Traffic events.
If public Traffic data is broadcast at your location, the software automatically takes into
account the traffic events received. You do not need to set anything in the program. The
receiver will automatically search the FM radio stations for TMC data, and the decoded
information will immediately be used in route planning. When your software receives traffic
information that may affect your route, the program will warn you that it is recalculating the
route, and navigation will continue with a new route that is optimal considering the most up-to-
date traffic conditions.
To fine-tune this recalculation, you can set the minimum delay that can trigger a route
recalculation, or you can instruct the software to have you confirm the new recommended
route before it takes effect. You can do these in Traffic settings.
A special icon ( ) is displayed on the Map screen to show you whether
traffic events are received. The icon shows the status of the traffic receiver when there are no
traffic events on your route, otherwise it shows the type of the next traffic event on your route.
Road segments affected by traffic events are displayed with an alternate colour on the map,
and small symbols above the road show the nature of the event:
