The past two days my deck has been acting very weird. I have a PAC-SWIPS interface for my Sony deck and have since March. I've had no issues or probs until two days ago when the deck, PAC-SWIPS, or steering wheel buttons developed a ghost. I'll be listening to music and then it's as if someone will randomly press a button on the steering wheel (no, I'm not bumping it). Tracks will change, the volume will go up or down, the mute goes on and off, etc. It's totally random and behaves just as if there's an invisible person who will just reach over and hit a steering wheel button. And it only seems to happen with a CD. I haven't noticed this with the radio yet. I don't even have the first clue where to start or what this might be. Any thoughts?
