Garmin 55 AVD Owner's Manual page 71

to accept the GPS 55 with the battery pack attached:
· Loosen the coinslot.
· Lower the cradle to its lowest position.
· Tighten the coinslot screw. When adjusted properly, the coinslot
screw should fit completely into the counterbore in the cradle so that
all surfaces are flush.
The surface mount has been designed for easy insertion and removal of your
GPS 55 if you wish to use the unit in another airplane, boat or vehicle, plan
at home, or prevent theft.
To insert the GPS 55 into the surface mount...
· Tilt the top of the GPS 55 into the surface mount as shown.
· Engage the slot in the top of the GPS 55 into the raised bump in the
surface mount.
· Rotate the bottom of the GPS 55 into the mount until the unit latches
securely into place.
· Connect the antenna or antenna cable. No other electrical connections
are required; all power and data connections are made through the 6-
pin connector installed in the surface mount.
