Ok I got a good plan now and I am just waiting for the screen. The screen will mount to the upper dash but will hang down over the center vent. There are three vents here a left, center and right. It will onlly cover the center one and I can do with out it. This will l also keep it from blocking any view of the road I have. If mounted to the top of the dash I would loose approximately 20% of the "road viewability". NOT GOOD
It will mount to the dash using a custom housing I will have to make. Shouldnt be too hard. One single cable will run along the bottom of the windshield and hidden under a rubber strip. Keeping the cable un noticable. I decided this to prevent drilling a hole in the dash. Parts for this car are damn near impossible to replace and if I decide to remove this computer setup I want as little repair as possible to do.
The housing I will build will atach to the dash with only two screws ideally and will be able to be removed very easily. When completed, I hope to have one bad *** looking setup. Looks good in my head now anyway.
