WTB compatible mp3 CD changer for e46 FL

[jon2367]

My CD changer has just given up the ghost. I want to replace it with a CD changer that plays MP3. I do need plug and play capability though - ie, I want the changer to slot in the original location, and don't want to splice and solder any wires.
Car is a '03 e46 with BMW business radio w/ tape deck. The changer connectors are the 3 and 6 pin ones.

Thanks & Merry Christmas.
