Im going to keep it as flush as possible keeping to the contour of the vinyl dash, but there will be curves and dips involved, ill try and keep it as flush as possible though to keep the OEM look. It will take allot of hand sanding to get it right, and it will dip to the center of the screen.
Reason behind the change is having a daylight readable screen. Having a console sized screen leaves endless skinning possibilities including split screen, multitasking etc. And how many people can say they have a 15.4" wide screen fabed into there dash? I also was getting sick of the small 7"er and just wanted to go bigger, and higher.
