wondering if anyone has found good use for the mini-cubby-hole/storage compartment.

I was thinking of installing a GPS in there that you could leave permanently and no one would be the wiser because you could just flip the cover closed when you leave the vehicle. Not sure if the reception will be good though. Would have to cut the back open to get you power source in there to look neat. Has anyone got the dimensions? I'd measure if I was at home.
