Printing a Mounting Template
NOTICE
These instructions for printing a mounting template must be followed precisely. Failure to do so may result in incorrect dimensions on the
template and an incorrect cutout (too large or too small) on the mounting surface of your boat.
To print the attached mounting template, check the dimensions of the template and select the appropriate size of paper. Both the length and
width measurements are indicated on the template.
The paper size must be larger than the dimensions of the template. Select the paper size using the Properties button in the Adobe Acrobat print
dialog box.
Select Auto-Rotate and Center to ensure the template prints in the correct orientation.

NOTICE
After printing and before cutting the mounting surface, measure the printed template to ensure both the length and the width printed at the
correct size and to ensure that the dimensions of the printed template match the actual size of your mount. Garmin is not responsible for any
damages or expenses resulting from a miscut mounting surface arising from a failure to follow these instructions.

CUT MOUNTING SURFACE ALONG
THE INSIDE OF THIS LINE
UNIT OUTLINE
Be very careful when cutting this hole,
there is only a small amount of clearance
between the unit and the Mounting Hole.
Drill four 3mm (1/8") mounting holes at the indicated locations.
Install the four Mounting Studs into unit by screwing the shorter section
in to the back of the unit.
Use a .050" Allen Wrench to tighten the Mounting Studs until the
stop contacts the case. Be careful not to overtighten as this may damage the
Mounting Stud! The studs have a reusable thread-locking patch pre-applied
from the factory.
Place the unit in position in the cut out in the mounting surface.
Place washers over the Mounting Studs, then thread on one Hex Nut per
Mounting Stud.
Tighten all four until the unit is snug against the mounting surface.
Install and tighten the second Hex Nut on all four Mounting Studs to lock
the first one in place.
Provide adequate clearance to press together the data card cover
handles and for the data card cover to swing open freely.
