Antenna Module (ATM) (2003-2006): Design: Am/Fm

The antenna module (ATM) consists of a thin film antenna and an AM/FM receiver. The control module can be upgraded with GPS and traffic message channel (TMC) units.

Information from the AM/FM receiver consists of radio signals received on the AM or FM-waveband.

The signal from the AM/FM tuner is transmitted to the audio control module (AUD) and infotainment module (ICM) via the MOST network.

If the antenna module (ATM) is not supplied with voltage communication on the MOST net does not function and the Infotainment system shuts down.
