Got a nbs 2500hd. I got a kenwood dnx7100 in it and the adapter thats needed for the onstar and tones keeps dying. It's covered by the stereo shopbut this will be the third adapter. Anyone got any idea's?

 

when i got mine hooked up we had to open three differant adapters cause they where fried allready and the installer said it happens all the time i would let them fix it againe then go to another shop mines using the scotche adapter
