I have this saying Navigation mount for 1 month in frequent use and must, I'm thrilled. It is in my A 180 centrally on the dashboard, which is slightly sloped. The Beanbag the chamfer does not fit, sits just two-thirds plan to, but he still does not move! The Navi sits absolutely firmly on the glass plate and does not wobble, is easy to use within reach. The Beanbag slips neither in sharp turns even when braking - great! I have some Navigation mounts through, but this is so far the best. And at the sight can get used to, so bad I did not find it. By firmly glued breakpoint neither Navi still Beanbag would fly during sudden heavy braking through the car, a further safety aspect. Genial!
