Car Stereos: cd changer, disc factory, pioneer stereo

Question
I just installed a pioneer stereo in my 2001 grand cherokee and noticed that its not running my 6 disc factory changer, i asked the installer and he said it will not work with aftermarket changers, there has to be a way!Its a Pioneer DEH-P5900IB if that helps! thank you

Answer
Nope, sorry, he's right. It's like asking an Alpine deck to control a Panasonic CD Changer.. totally different platforms and interconnects. There were a a few factory decks that could control aftermarket CD changers with interface adaptors, but to the best of my knowledge, I've never seen an aftermarket deck control a factory changer.
Maybe try contacting Crutchfield at www.crutchfield.com to see if there is any special adaptors made for that.
