I'm just guessing but it looks like the suction cups are up against the edge of the head liner and the unit is up against the rear view mirror. So really, the suction cups might not be doing much of anything - the unit looks wedged in and the suction cups just provide a point of contact to stabilize things. I looks like it works.
