This is made for Mini 080X dashcam. The idea is to stick an action camera slide mount to the windshield and stick the dashcam's GPS mount to this thing. Then it is easy eg. to move the camera between two cars and you don't have to stick the GPS mount direct to the windshield and loosen the contacts by time. Also, with this thing there will be no metal near to the GPS antenna.
