We have a Tom Tom. I mounted the little round plastic pad that came with the device to the top of the dash. It works just fine. I attach my Furrion Observation camera monitor directly above it on the windshield. It's between the rear view mirror and the Tom Tom this way, slightly to the passenger side so I can see the entire hood of the truck. Never had a problem. A little spit on the suction cup and they (both) hold just fine!
