If it helps in any way, I can only confirm that I haven't a clue. May well pay you to fit an alternative unit. I have a good contact for Blaupunkt units, and they are well priced with good quality. Regards Styria
Tim $110 is a very reasonable quote. As most places now charge over $100 an hour for Labour. And it will be repaired by a specialist to the product . Most trade places you go to will charge that to look at it.
That was not what I was thinking of.
I assumed there must be a plug/socket connection in the boot somewhere .
If you were going to have the unit serviced it would need to be disconnected .
I was proposing you disconnected this connection point in the boot and then reconnected it. It should not affect power to your radio. I am not familiar with the set up,It was a suggestion only if it is not applicable just ignor my comment.
Kind regards Jim
