I have a radio that I just took out so I could install factory AM radio, lol. It is an older head unit with a cassete deck, but it works and plays fine. You can have it if you want it. Buy an FM modulator for $20 and you can play your MP3 that way. I use an FM modulator in my daily driver and listen to satellite radio/MP3 from my phone. Mine is similar to this one...
