I was going to replace the Becker Cassette/radio with an aftermarket CD/radio. Pulled the unit out of the dash and that is as far as I got. Thinking about other posts, I am guessing that the assembly in the dash is called the head, the tuner and amp are located somewhere else. Is there an easy way to install the aftermarket CD/Radio or do I need to run new speaker and antenna wires. Is there a reasonably priced CD/Radio that will plug into the existing set up or can I add a cd player to the existing radio/cassette. I want a single disk unit, and would rather not have it in the trunk. Thanks for the help and advice.

You've got mail, can not post answer without getting in trouble.

Ken,

If the head unit you removed doesn't have an antenna connection, then the tuner is in the trunk (right side between the hinge and the fender)and the amps are behind the rear seat. You will have to run speaker wires at least to the amps, an antenna cable, and possibly a signal wire to the antenna.

I don't know of any drop in in-dash CD players or wiring adapters to make an easy job of it... and I've looked.

One option is to get a portable CD player and connect it to your system by a cassette adapter (I've heard some MB head units don't take these, but maybe it's the later models) or an RF converter (~$20 at Radio Shack).

I have an RF changer in the trunk and it was pretty easy to install. I didn't touch anything in the dash.
