How heavy is it? I'm not keen on loose objects in cars that have much
mass. Have an accident (rolling, or becoming airborne shakes things
up nicely) for any reason and they end up flying about at relatively
high velocities, ie. the car and you (as you are strapped to it) have
slowed down or stopped but loose objects haven't. I wouldn't like to
be hit on the head by a ricocheting satnav doing 30 mph...

This comes from experience of hitting a (small) tree, rolling a car,
and watching the play backs of cameras mounted in cars for various TV
stunts. Any loose really does fly about all over the place.
