Audi 2007 Head Unit Change
I was hoping that someone might help me with a problem.
I recently changed the head unit in my A4 for a JVC KD G821 unit. This is so I could plug my IPOD in and play it straight fron the head.
PROBLEM: When the car lights are on there is a slight buzzing sound that comes from the speakers (I have the BOSE system fitted). This disappears when I switch them off. I have auto sensing lights and even when they are off and the switch is in the AUTO position the buzzing still persists.
Has anyone else had this problem with head unit changes? Is there a way around it? Will I have to get night vision in order to drive around without my lights?
How have you linked the new HU to the Bose loom?
In all cases of interference/buzzing/whining it's worth earthing the HU chassis to the chassis of the car.
