Traffic Message Reception
The traffic message signal which is transmitted via radio is received by the antenna. The signal is sent onwards via the antenna amplifier (16/16) to the traffic message channel module (TMC) (16/49). The traffic message channel module (TMC) sends the signal onwards via the MOST network to the receiver in the multimedia module (MMM) (16/108).
The multimedia module (MMM) presents this information on the directly connected display (16/46).
