Are you looking to make your own kit? This product is the best way to mount that GPS and most electronic device's cradles.
 
The Square AMPS Hole Pattern Cradle Adapter is  2" x 1"5/8 square base with a 1" diameter rubber ball connected at right angles. The base has a hole at each corner, making the universal 1.5 x 1.188 (hole spacing) AMPS hole pattern. It's a sturdy aluminum construction to keep the weight low with a durable anodization finish.
 
This AMPS standard is compatible with almost all GPS cradles, InReach docking base, Phone cases, and more! Check your device specs if unsure.
 
A non-exhaustive list of devices would be the Garmin Zumo, TomTom Rider, InReach Explorer+.
 
Note: This can also be used as a base, bolted on a flat dashboard if needed. 
 
This product is only a cradle mount (or ball base), within the ball mount system. You may need to purchase other components to complete your setup.
