The role of the TMC receiver is to receive traffic information on the FM wavelength. The Japanese system is called FM multiplex.

The TMC receiver is integrated in the RTI system and is connected to the antenna system for the FM radio.

There is no traffic information system in the USA. 

The TMC data signal is received by the TMC/FM multiplex antenna (16/68) which is located in the rear bumper. The signal is boosted by the antenna amplifier (16/67) before it is sent to the RTI unit (16/45). This data is displayed on the screen (16/46).
