Jimmyfloyd and I talked about installing a single DIN AM/FM/DVD headunit and a 7" screen below. The headinut would have to be mounted as high as it could go in the 1.5 DIN opening so the LCD can fit as a surface mount. This would be much cheaper than a motorized in-dash 7" screen.
A double DIN unit recently fell in my lap and I've successfully mounted it in a modified dash with a modified trim panel (see here
for pics). The trim is in the final stages of completion but I'm still waiting on some spray texture. As we speak I'm working on the HUD switch opening.
