I know what you mean; I have an 05 GT, and I wanted to switch my OEM stereo (shaker 1000) for the 07 version. The reason being, I would gain Sat Radio capability...The guys at the Ford Stealership told me its not a an easy "bolt on" swap. Probably what 1kwikv6 was talking about. Im currently looking into a modest, and clean looking Double Din touch screen to toss in. The benefit of Cost/sound quality ratio is really on the side of Aftermarket...Im looking at something along the lines of the Kenwood DDX318 (link below) Be warned though, some of the extra parts (wiring harness and stuff) can add up fairly quickly. So ya, in the same boat...Hope this helped. Kenwood DDX318 DVD Receiver
Good luck either way; Keep us posted.
