FYI
You might want to go to a dash mount. It is illegal to have anything on your windshield in many states and some states regulate where on the windshield you can mount anything.
Because even a 5 inch screen GPS on the bottom of your windshield could block your view of a motorcycle according to the Arizona Highway Patrol officer that issued me a warning ticket for my illegal GPS mounting.
Even though my GPS is in the same location but because it is now on a dash mount I now can see motorcycles.
