My control head is inoperative, the red light on the circuit board turns on but nothing shows up on the screen. The control panel has been replaced with new. The control head is not reachable using VCDS.

The control head box itself stays pretty hot even when the car has been off for a while. I tried removing the board and cleaning off what looked like corrosion.

If you have ideas for fixing my control head or have a working one let me know.

I donít want FBAS or anything. Really Iím looking to sell the car and itíll be easier to sell with a working nav/radio system.

This is for a 2006 A6 4.2.
