I have a Freestar limited with a 6 cd radio, dvd and controls on the steering wheel. The cd is dead. (always displaying ''check player''). My model # is 3f2t-18c815-ee. I'm looking for a way to fix this by opening the case and looking for a stucked part but no luck. Everything looks perfect. The others features of the radio works perfectly (radio, dvd, steering controls). so i wanted to find a spare one and by the same time adding the mp3 feature to my car. My problem is: i found the same looking radio and same rear connector but there's so many different model number. which one to choose?

Any idea?
