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) 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) (16/105) then sends the data onwards via the MOST network to the infotainment control module (ICM) (16/1) which in turn transmits the data onwards to the selected sound source.

The sound sources which can be selected are:

• radio (ATM) (16/110)
• CD player (MP2) (16/106)
• MD player (MP1) (16/107).
