sounds like the radio face didnt go back on correctly.

buy a car lighter MP3 adapter from your local electronics store. It plugs into your cars cigerate lighter and sends a radio frequenzy to your cars fm stereo without wires to you stereo, once setup push the seek button on your stereo and it will search for a station your mp3 is registered to.

get a new one as they are cheap these days!
& not worth the labour costs to try & fix them anymore!
