Have you tried contacting a Chrysler dealership in the UK? I thought I had this problem because my radio would not operate, so I tried to get a code from the dealer that sold me the car. They said that the European cars needed a code, but the American models don't need one, so I came to the conclusion that my radio was toast. I believe your best course of action would be to contact Chrysler ... or put your headphones on
