04, 6spd gt, single disc bose stereo, 38k miles, no head unit modifications, never even had the dash panel off.

Everything worked fine the night before, nothing weird happend, didn't hit any bad bumps or anything. It was cold overnight, about 2 degrees F'
I start it up the next day about 25 degrees out, and let the engine run a little before turning on the defroster as usual, except now none of the controls work except for the fan speed and temperature. Then I notice the stereo buttons don't work except volume and eject button. The stereo will play the cd i put in, but I can't skip tracks or adjust bass/treble. The buttons on the steering wheel don't work anymore either.

First thing, I checked all fuses- All good (Metered not Eyeballed)
Second, Disconnected battery thinking a reset would help, NO GO
3rd, Read some discussion in these boards of people having similar problems after undergoing modifications to the dash/head unit, which I haven't done. But still I checked to make sure the faceplate was secure and tried pushing slightly in the corners of the cd player/dash like some suggest the connector being loose. Doesn't seem to be my issue. I don't have a garage so I've been putting off tearing out the dash and unit to check all connections, I'm hoping somebody found a simple cause for this before I go through all that. Essentially any solution other than buying a new unit would be a weight off my shoulders.

Thanks for any help you can offer

 

Anybody? Anything?

First: Check the plugs on the back of the head unit.....
