Source a Garmin Aera 660 mount for light aircraft and use a dremmel to remove the little plastic tag on the bottom centre of the mount. Then it will take your Garmin Zumo 660.

The Garmin Aera 660 aviation mount will take our 660 Zumo devices: just need to remove a little tab on the bottom of the mount, with a dremmel or similar.
