If one engages in the Holder the Garmin GPSMAP 62 (which does not work as good as the original) snapped this Holder of the adapter plate: The Navi gets dropped. A bad design! One could first Navi snap into the mount frame and then push it into the adapter plate, but the holding forces of the detent are far too low, as that I would drive off with it. Have Halteschale and adapter plate bolted together, but I am so unhappy with the overall functionality, that I will not use it. Conclusion: well-intentioned, but poorly done!
