[QUOTE="aidilj, post: 575702, member: 20536"] Hey bro, the diagram as below. If you suspect that the wiring at the head unit is messed up, it is probably related to IBUS. Disconnecting IBUS at the head unit should get everything working again. The IBUS is a network where not-so-crucial components of the car use to communicate with each other, see 2nd picture.
