At least lock it in the glove compartment (after getting a secure aftermarket glove compartment)
Do you have any links, sources, etc to aftermarket glove box manufactures? I was thinking about that myself - I lock mine in my glove box when I have no choice, but I have no delusions about how weak it is - sternly talking to it, and the lock would pop open!
However - just locking it up, or taking it out of the vehicle isn't enough - you want to stop someone from even wanting to bother smashing your window to get in, cause they think you may have left in under the seat, or in a weak glovebox.... hence the phony face-plate.
