I installed a BlueMusic Bluetooth adapter in my A2 a couple of weeks ago. Plugs into the back of the radio (Concert 2)
Tested it before I slid the radio back into place and all was well, but I didn't have the engine running. It seems now that if the engine is running then I get a high-pitched humming from the speakers in the rear of the car. This happens whether the radio is on or off.
If I only have power on (no engine running) then the humming stops.
Any ideas?
