That is my concern. Do you leave a GPS out in plain sight or do you have to hide it every time you leave your car?
Now it only goes in the car when I think I am going to need it. Back then though, it was entirely out of sight(cables, mount, all of it)...except for the rings on the window. Get the beanbag. Had I gotten that, I might still have my 350, of course the thief did me a favor..the 750 has a bigger display and routes.
