My pionner headunit is getting a little old now but I don't want to waste money buying a new one but here's the situation: at first, the left side of the headunit didn't work anymore but I didn't really care cause it was only for the volume buttons. But now, even the right side doesn't work anymore! That's a bigger prob cuz I can't see anymore, the # of the track, the volume #...What can I do?

 

well i doubt it will help, but try cleaning the contacts where the faceplate meets the radio on both sides, that is, if it has a removable face...
