Travel Message Channel (TMC)
The TMC is a component of the Radio Data
System (RDS), which is transmitted by the
radio stations.
The information in the TMC includes the loca-
tion, type and duration of traffic hold-ups
reported by the police, automobile associa-
tions and government authorities in a coded
form standard throughout Europe.
The TMC data is not currently transmitted by
all radio stations.
This requires the use of a second tuner in the
radio or in the interface of the Navigation
System Plus.
As only the symphony II radio is equipped
with a second tuner, the use of TMC data for
dynamic routing is only possible with this
version.
Dynamic routing in conjunction with the
chorus II and concert II radios is only possible
by means of the traffic messages via tele-
phone with telematics
Diagnostics
The navigation system diagnostics is interro-
gated via the L-wire.
