Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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) 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).
