Welcome to the world of CarPC's.
I've got the dynamix 816, and I would definitely recommend you make sure the thing stays cool. It's a great screen, but when it gets hot, the touch panel de-laminates and you lose calibration. If you keep it cool though, you'll be fine. I had to cut a hole in the back and install a fan, but it wasn't easy.
If you're dash looks like this one:
You will most likely have space issues. the screen will fit, but not the buttons, and you'll have to find a way to hold it there since the housing will most likely not fit either.
I'm interested to see how you do it. BTW, I don't think anyone here cares what you drive, it's that you are interested in the same thing - Car Computing...
