Checked them out. The gps based is definitely not cool. All of these seem to plug into the cigarette lighter. Also not cool. Lol. I wanted something like the camaro has.There are a few available on Amazon. You can search "heads up display" there. Some are GPS-based, whereas others are OBD II-based. Mostly $100 or thereabouts, I think. Go check em out. I was thinking of buying one at one point.
