Selecting The Sound Source And Track From The Headset Panel

There are two identical button arrangements (16/111, 16/112) on the headset panel, one for each socket. These buttons are used to change the sound source and track.

When a button is pressed on the headset panel, the audio module (AUD) (16/105) identifies which button it was. This signal is transmitted between the headset panel and the Audio module (AUD) on a directly connected cable. The Audio module (AUD) then transmits information on, via the MOST network, to the Infotainment control module (ICM) (16/94), which, in turn transmits the information on to the selected sound source.
