How large it is? I was wondering if I could hide it in the ash tray with some mods to the tray.
Overall is 2 1/8"x 3 1/8" Held on with some command strips. It's very temporary and I don't like it, but it works if ya don't mind subtracting 1.5-2 mph off the displayed speed every time. Plugs into the 12v cigarette lighter socket, so there's no wiring to do.
