Greetings all. I have a 02' C230 Sports Coupe. I have the factory CD changer installed. Does anyone know if there is an attachment or customization that will allow me to use an MP3 player like this one (the 60GB capacity of course):

I know there are tape adaptors, but I'm looking for an "all digital" method. Any replies would be greatly appreciated.
