There has been a big rise in stolen GPS units of late. The suction cup is a give away, even though you remove the suction cup, it leaves a mark on the windshield. You may not want a suction cup mount because of this, as well as they do loose their grip over time, due to variation in temperature. If you take the mount off and leave your radio in the car, it will be a target of a thief. The cup holder mounts are also not good because they don't seat properly. And the grip type mount wears out a lot faster than you want to, and you'll keep replacing them. if you find the PanaVise ClipCaddy in a store, get that instead. Mount it on an angle bracket off your dash and you won't have a worry. The belt clip fits into it nicely. And it doesn't have grip failure.
