there is another thought though - cd players are out dated fashion. my car have it but i just don't bother to use it, what i am using the most is the mp3 player/transmitter, which produces cd-like sound quality and easy to save/update files to. i am using one like this: In-car mp3 player

(remove * then add . before "com" otherwise i can't post it)
good luck!
