Real-time traffic information (TMC)
TMC ( Traffic Message Channel) offers real-time traffic conditions. This
can help you to avoid traffic jams th at could not be anticipated due to
road closures or accidents.
TMC uses a dedicated XM satellite ra dio to broadcast real-time traffic
information.
The default settings use traffic information when searching for a route.
If traffic data normally broadcast in your region can be accessed, this
received information is automatically taken into account. This does not
need to be manually set. XM sate llite radio stations broadcasting TMC
data are searched for automatica lly, and decoded information is
immediately used to search for routes . If traffic information that might
affect the current route is received , a warning is displayed indicating
that the route will be searched for again, and navigation continues
using a new, optimal route taking into account the latest traffic
conditions.
By delaying the timing before applyi ng a route that has been searched
again, the user can check the route and fine-tune the details creating
the optimal search results. You can se t this from Traffic settings. (See
Page 158.) When traffic information is being received, a special icon ( ) is
displayed on the map. When there is no traffic information available for
the route, this icon indicates the status of the traffic information
receiver, and when information is rece
ived, the type of upcoming traffic
information is displayed.
Road sections affected by traffic co nditions are displayed in a different
color on the map, and a small icon representing the type of traffic
condition is displayed above the road.
When the traffic information has be en received, the icon displayed
on the screen changes to the icon.
To check traffic conditions outside the display, touch . The Traffic
Summary screen is displayed.
