Just finished installing the digital DIC and HUD in my 02 gt. never would have considered it without this writeup. Everything worked great first try. only a couple issues:

hud is always on km/h when i start the vehicle. Switches to mph after a little bit.

Put the radio back, backlight stopped working. pulled it out and put it back, backlight works. had to pull it out and put it in for something, backlight stopped working :/

I'll look into it a little more tomorrow. other than this the whole install was flawless. I can see the HUD perfectly on the 'regular' windshield.
