The factory stereo in the current Escape, Focus, Mustang, etc. is a true double-DIN. The one in the CV/GM, despite its appearance, is not. Mounting a double-DIN stereo would require some degree of dash bezel modification in order to fit. Crutchfield just says it won't fit. You could put a single-DIN replacement stereo in there, although I have never been fond of the appearance of a single-DIN stereo with black plastic all around it filling up the space from the larger factory stereo, but that's just me.
