Fed up with your original TomTom push-on mount falling off the windscreen? Then swap to our Lever-Release arm that gives reliable, dependable suction to glass, friction / beanbag mounts and dash / console discs. This mounts design is based on the original TomTom GO mount but instead of relying on your "brute-force" to push the arm against the windshield it has a lever to expel air and create a vacuum that holds the arm securely until you want to remove it. The arm comes with the slot in holder that fits the TomTom GO 520, 520t, 720, 720t, 920, 920t and the TomTom GO 530, 730 & 930 Traffic.
