Thanks for the info, but this is not exactly what I'm looking for.

I'm not looking for a way to replace the standard headunit. My dad would never allow me to do that. He doesn't like his car to be tampered with. I've already had to use every ounce of persuasion power I have to convince him to let me install an Empeg in his new car. ("No dad, this isn't going to scratch your dashboard", "No dad, this is easily removable if needed be", etc, etc...)

So what I'm really looking for is an adapter which could turn the interface for the CD-changer into an AUX-in input on the standard head unit.

I guess if I really had to I could also go the FM modulator way, but this is something I *really* want to avoid.
