My P38 harman kardon radio CD/FM channel buttons have stopped working. And now its stuck on short wave AM. I have removed the radio but all the wires look fine to me. any one have an idea please say.
Thanks.
If you mean the buttons on the Radio itself, could be the radio has failed. If there are duplicate buttons on the steering wheel, it could be one of those buttons or the rotary coupler.
As mentioned by Datatek if it is the clarion diversity unit they will referb it like new for about 150 , worth doing as they are a nice unit and cheeper than trying to fit aftermarket unit to work with the system.
