anything you can think of has probably been done before
i remember seeing this picture online so i grabbed if for you
its a little harder to do in the 96-98's cuz of the climate control setup, but one thing i have seen only once is a technique that people rarely think of. in japan the 96-up civics have optional navigation, it goes in the same area as the climate control, i believe it is a 6" screen...if you can find one of these oem parts and use it for your own purposes i think that would be cool......sorta
