Ok, so I've had my Sony CDX-M630 CD player with a fold-down faceplate and just a few weeks ago the buttons wouldnt work and I have to use my remote to use and now none of the lights are working but I can still "guess" on which station I'm on. Is this a problem with my CD player or my trucks electrical system?

 

It's the head unit, I threw my sony out the window for doing the same thing! At least I got two years out of it!
