I had this reoccuring problem during warranty coverage & afterward. I probably used the cd player 20 times before it would jam. I went to a local stereo shop & had a Pioneer unit installed. They carry all the adapter plugs. The only item I had to supply was a ( double din) face plate to mount the stereo. No one seems to sell one but I found one on Ebay from China for $50. I have had no trouble with the aftermarket system for the last five years.
