MMI 3rd Generation Components

The audio output in the MOST system has many control modules which are interlinked with individual vehicle systems. These control modules communicate with each other via the different bus versions. The data bus on board diagnostic interface (J533), which is connected to all the different bus versions, processes the data and sends it to the control module.

• AWD vehicles also have rear ABS wheel speed sensors (G44, G46).

• The Premium Sound System is shown in the illustration. The sound amplifier is integrated with the radio (R) in the Basic or Standard system.
