Garmin GPS 120XL Owner's Manual page 61

To flush mount the GPS 120XL:
The GPS 120XL can be mounted flush with a flat
panel of .08-.52" thickness using the cam lobe feature
on its mounting bracket.
1. Cut a 4.15" W x 4.67" H hole in panel.
2. Place GPS 120XL into hole from the front until its
flange rests against the mounting surface.
3. From the back side of the panel, loosely attach the
bracket such that the slot in the ratchet area points
away from the mounting panel.
4. Rotate the bracket downward until the panel
is pinched tightly between the units flange
and bracket lobe.
5. Tighten knobs and connect the power/data
and antenna cables. Note: If the panel is too thick to
allow use of the knobs supplied, use two M6 screws
to secure the bracket.
