The Dog Ears plate is made of machined aluminium and replaces the broken plastic tabs on your Garmin GPS device. Remove what’s left of the plastic tabs and place the Dog Ears plate over round part at the back of the Garmin, using the 2 small screws to fixate the plate and a couple of drops of superglue to secure it. The screws do not penetrate the case deep enough to damage the working parts of the Garmin.
