Car Stereo Replacement

I have a 2004 GP and want to replace the original stereo/cd player with a pioneer head unit. Has anyone attempted this? And if so how much of a pain was it to do? Is there any sites with info on installing a head unit into a GP? All the sites that I have been to skip over the G.P.!

Crutchfield usually has good info on aftermarket radio swaps, including wiring harness and mounting adaptors needed to do the swap. The radio looks like a straight-forward install according to the GM computer, but to retain things like your steering wheel controls (if equipped), you'll need a separate adaptor.

I was going to do the same thing, until I found out that you will lose the calendar function of DIC. I did not find any adapter that will replace that function. The stereo swap itself looks simple.

Leave it to GM to make a simple upgrade not so simple. My cousin has a Taurus and the radio is integrated into the dash/heater controls, so I guess it could be worse. I wish GM would quit shooting itself in the foot like this.
