Tmc (Traffic Message Channel); Tmcpro (Optional) - Medion Navigation Unit Operating Instructions Manual

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
people driving on the wrong side of the road for example, 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.

TMCPro (optional)

TMCpro (a service of T-Systems Traffic GmbH) mainly uses an automatic system to record
the traffic situation, while the normal TMC relies on information from the police, ADAC
and reports of traffic jams. Sensors on autobahn bridges, strips of sensors set into the car-
riageway and a large number of vehicles equipped with 'Floating Car Data' technology
quickly supply a precise and more current image of the traffic situation on German auto-
bahns, including predictions of possibilities.
Your navigation system will support both services and is set for the reception of both of
them in the status at delivery.
