Hello everyone, this is going to be my first pictorial DIY so please take it easy on me :P I have done a lot of mods for my car, on my own, but was always too lazy or excited to take pics. I know some people wanted to do this and needed information on it. Oh, btw, please excuse the dirtiness...

at the moment using FM transmitter by belkin - its crap 01/02 320ci stock standard single cd BMW business CD player (no stacker) what are my options? (excluding aftermarket headuints and crap, want to keep it as OEM a possible) thanks guys:):)
