I have a 2006 Forenza. The original stereo in it acts up sometimes, meaning the CD player won't play the cd's half of the time. I'll put a cd in, and it'll play for half a song, then it'll stop and spit it out. The stereo doesn't feel hot, and I can't find any other reason then maybe it needs to be cleaned. Has anyone else had this problem with their CD players? Would it be easier just to change out the entire unit?
