Have different products compared and was not quite sure if that in my Passat (dashboard little curved and not completely smooth) would really hold well. The nipple of my Navigon has not kept quite on the disc, feeling sometimes conflicting overthrown. The Tomtom on the dashboard holds far bombig (neatly cleaned before the dashboard!) (Summer and winter) and the old Navis Auger stops on the plastic disc completely reliable, unlike on curved glass, especially if you are the holder not permanently removed. On the dashboard, the holder bothers me less than on the disc, even though I myself do not often need the Navi, and then of course not affixes.
