Ok, my 98 5 Series has a casette deck. Sitll confused as to why a cassette deck but anyway I would like to know if I could change the cassette deck into a cd changer with mp3 playback. Where can I purchase a good quality cd player where I can play mp3's etc???

Instead of doing the trunk cd changer I may opt to just do the cd player.option, which I do believe that is easier to do. Please provide a website recommendation for the cd changer.

Once again, thank you all for the help. This site has been a God sent!!!
