Cannot Control Head Unit

[seeth001]

I installed a new Pionner DEH P6200BT on my 2002 Grand prix and it had no problems until now. Its been 6 months and now all of a sudden the lights on the head unit are off even though the system is working, meaning i cannot control the unit. Also it starts working again fine every now and then. this is really irritating, can someone please help me. thanks!

Sounds like dirty contacts on the removable face.

Take the face off and spray the contacts off on both the HU and the face with some contact cleaner (Radio Shack or most hardware stores will have it).

Then after it dries carefully snap the face back on and off a few times to further loosen any crud, then try to play it again.

Ah, I was thinking it was some other kind of problem. So the HU can get dirty and cause that? didnt know that.. I will go buy some cleaner and try it out. Thanks
