All - just sold my beatup ol' '00 GP GT and replaced it with a '03 GTP.

I know this type of question has been asked before, but I've become accustomed to having a CD-Changer (12-disk Pioneer/GM factory) for 10 years (had a '97 GT before the '00).

The new(er) GTP has a factory CD/EQ indash, and the dealer I traded the old car to let me keep the CD Changer.

Now, I know the indash CD and CD Changer don't like to 'play nice' together, but I was wondering if anyone figured out if a physical switch might resolve that by basically, disabling the indash CD (SP/DT switch, probably) and turning the Changer on at that point...

Just a crazy thought...

Hmm that's a question I haven't seen yet. I have no clue but welcome to the site. Nice to see another GTP in the midst.

No clue welcome aboard .Chico.

You could get an FM modulator so that you could use the CD player on an FM frequency. Or just spend 100 bucks or so and get a decent aftermarket pioneer HU. Welcome to the board.

Theres no really easy way that I know of. You might have to replace the dash unit with a casette player for it to work. Having onstar might effect the posibilities too. Don't give up.
