  Go ahead - Connect to a 17mm diameter ball-type socket.  Install the 17mm diameter end of the metal connector in any socket (of a ball and socket joint) on GPS or similar devices. Install the 20mm end into the end of a carbon fiber series fixed arm. May require you to purchase a Garmin accessory to get the attachment with the 17mm socket. For example, a suction cup accessory.
