Its a little box about the size of a pager that sits on your dash, and a strip of scotch tape looking stuff you put on the glass. Not too bad - 2-3 hundred and they monitor a bunch of stuff. I just don't think the daylight reading is very nice. A buddy has that one for his Volvo, but he still hasn't installed it.

The factory GTP HUD is actually really nice.
