What Other GM Radios Will Fit

Hi
2004 GP here, looking to replace my stock radio, the CD player is going, but have found it to be too much trouble to wire up an aftermarket head unit. What other GM vehicles have radios that can be simply hooked right in with the existing harness? I know i could find another unit made for this car but I hate the Pontiac red display, i really like the blue/green chevy ones.

Basically, what other GM cars have identical harnesses, and which ones will not piss off the PCM?
 


why not just buy a used radio like you already have, that way you know it will fit/work. im sure theres more then one for sale on ebay.
 
Not sure how true it is, and the information pool on here doesnt seem definitive on it, but I have been told that any Class II radio will work and not cause problems with the vehicles systems.
