I reported twice to my dealer that I had this problem and they told me they could not do anything unless I could duplicate the CD jam (error 4). Last week it happened as I was driving through town and I pulled up to the Lexus service station bay and oh ya they could see the problem. Mileage was 55K - 5K past warranty and it would cost me $700 to repair. Not mechanical and certainly not happy. Do not use an Ipod
