Anti theft GPS?

I suppose it would work. It only needs power and ground from the OBD port, which are, of course, available. Not sure how useful it would be to have a box like that sticking out at the driver. I imagine a thief would just rip it out and throw it out the window.

It would be more useful for insurance companies and loan companies, as the person with it would be willing to keep it in there if it meant insurance and loans were still valid.
