Drill a 1-inch (25.4 mm) hole in the dash for the power and antenna
cables. The best location for this hole is immediately under the gimbal
bracket location. This way, the bracket can be installed so that it covers
the hole, holds the cables in position and results in a neat installation.
Some customers, however, prefer to mount the bracket to the side of the
cable hole — it's a matter of personal preference.

GlobalMap 3500C when mounted on gimbal bracket.
After drilling the hole, pass the antenna connector up through the hole
from under the dash. Pass the power cable's bare-wire end down
though the hole from the top.
If you wish, you can fill in the hole around the cables with a good marine
caulking compound. (Some marine dealers stock cable hole covers to con-
ceal the opening.) No matter what type of installation you prefer, be sure
to leave enough slack in the cables to allow tilting or swiveling the
GlobalMap 3500C. If you choose to fill in the hole, be sure to position the
cables against the rear edge of the hole as you apply the fill material.
Before positioning the bracket, be sure to hold the cables against the
rear edge of the hole. Then, slide the bracket over the hole and butt the
rear of the bracket base firmly against the cables, thus pinning them in
place against the side of the hole. Finally, fasten the bracket to the
dash. Attach the unit to the gimbal bracket using the supplied gimbal
knobs and washers.
