I did not want GPS in my field of vision priority (suction cup on the windshield). Besides my Volvo has a strong inclined windscreen which positions the GPS too far from the driver for good visibility. This adhesive achieves parfais plate holder on the dashboard and the TomTom 135 it locks the same way that windshield while being removed from the holder at any time. After some trial "blank" (without removing the protection covering the adhesive at purchase) to find the best position on the dashboard, I glued the plate without remorse to the most suitable place , allowing me to steer the GPS in my direction with the right angle. Much closer to me than the windshield and without being in my field of vision "road". Tip: Make the white positioning trials sitting in the car. Once stuck, it's ... stuck. :-)
