Garmin eTrex to quarter turn adapter

Note: uses the flat head screw from the original Garmin clip adapter. This adapter is designed to fit older Garmin eTrex series GPS devices to standard Garmin quarter turn accessory mounts. It allows you to use any current Garmin quarter turn cycling mount, which are much more elegant than either the original Garmin eTrex handlebar mount or aftermarket RAM Mount solutions. I designed and tested this with a Garmin eTrex Legend HCx. It will work with some other models that have the same backplate with removable clip but some of the eTrex series have a built-in clip, so it would not be compatible. I tested on a couple of road rides and one mountain bike ride. The Garmin didn't move at all although the click-in engagement felt a bit softer than an original Garmin quarter turn would. Always use a tether!
