TMC (Traffic Message Channel)
The Traffic Message Channel (TMC) is a digital radio data service that functions in a
similar way to RDS and is used to transmit disruptions to traffic to a suitable reception
device.
The traffic information is continuously transmitted across FM.
The user is less dependent on the half-hourly broadcast traffic information, because the
signal is continuously transmitted. Apart from this, important information, as in the case of
an accident in the road ahead, can be passed on immediately.
The transmission is planned for the whole of Europe and is already offered by radio trans-
mitters in many countries. The precision of the TMC messages can deviate greatly accord-
ing to the country.
The evaluation of TMC messages is not supported by every type of navigation software.
Enquire whether your system supports TMC before the possible purchase of a TMC re-
ceiver.
