route outline even if the GPS signal is tempo-
rarily lost, e.g. when driving through a tunnel.
Traffic information
TMC (Traffic Message Channel) is a standar-
dised coding system for traffic information. The
receiver automatically searches for the correct
frequency. Reception takes place via the FM
antenna.
NOTE
TMC is not available in all areas/countries.
The system's coverage area is under con-
stant construction and updating may some-
times be necessary.
For information about updating map data and
