24. TMC (Traffi c Message Channel) (optional)
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 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
transmitters in many countries. The precision of the TMC messages can deviate
greatly according to the country.
PLEASE NOTE!
The car adapter has got an integrated TMC antenna within the cable.
TMC can only be received, if the car adapter is connected.
24.1. Premium TMC (optional)
If your navigation system features premium TMC, you will obtain more accurate
TMC information provided by NAVTEQ Traffic. Your MEDION GoPal utilizes this
information at no extra cost. Depending on your configuration this premium TMC
information is made available for the corresponding countries.
Standard TMC information is provided by police, automobile clubs and traffic
reports, while premium TMC-services mainly rely on automatic traffic monitoring
systems.
Sensors in highway bridges, sensing loops embedded in road surfaces and a
large number of cars equipped with „Floating Car Data" technology quickly
generate precise and accurate views of the traffic situation on highways as well as
predictions.
Your navigation system will support both services and is set for the reception of
both of them in the status at delivery.
