When I pads taping it (in two different cars) on grained surface and then the mount my TomTom fortified on all bombproof was installed. The touchpad of the Navis was properly operated. However, two days later went up the outside temperatures and the heated windshield, the dashboard ... because I had the whole installation during the trip counter. The glue under the pads can withstand well any heat. Evening in cooler outside temperature everything was firmly back on and then stops again until the next heating. Since the drop of the complete Navis represents a significant traffic hazard while driving, support should be provided as mounted on the windscreen.
