This mount will simply clip onto the Garmin mount using the same locking mechanism as is used for the Garmin Zumo GPS.  It can then be simply removed using the same mechanism by pressing the top button on the top of the Garmin cradle.

In order to use this with your Quadlock device, you will need the normal Quadlock mounting parts such as a Quadlock lever head.

For reference, the Garmin cradle it is compatible with is:

If you are mounting a phone, I always recommend you use a Quadlock anti-vibration dampener.

No mounting hardware is provided, as the length of M5 bolt you will require will depend on the Quadlock setup you wish to use.

This adapter is 3d printed and is made from black ABS plastic (the same type of plastic as is used on most motorcycle body panels etc).

These are made to order so there may be a small delay between order and shipping.
