Have a Sony xav-3600 and SWC worked fine, but now they act like there all depressed. Turn radio on, turn up volume, it automatically goes down! I can buy the rubber covers but has anybody had this happen, and what dit it turn out to be?
The original headunit does have a switch-status diagnostic screen where you can see just what buttons it thinks are pushed and when, and that can help a lot in tracking down what's going on in a situation like this. Of course I know nothing about the aftermarket unit you've got, but maybe it has a similar screen you can pull up some way.
