I have a Kenwood receiver in the Supra ( i believe the factory unit from 03)and the buttons no longer respond to anything--followed the manual and hit the reset button but it did not make a difference--any one know electronics?

take the face off. get a tooth brush and wd40 cleanthe conections

thanks I will try that--phil

cleaning did not work--any other suggestions?

im having same problem. I can some times get it to work for 10 min and then it will quit. I have a 03 moomba with the kenwood head unit.

I tried it again yesterday and when I push a button, the whole thing turns off--I guess it is time for an upgrade and I just figured out how to use this one--
