Mounting the Receiver
Please read through these instructions thoroughly before
attempting installation. Make sure you completely understand
these instructions before you begin. When in doubt, seek profes-
sional assistance.
The following additional items are needed or optional to
complete the installation of your GPS 17:
• Antenna mount— Since antenna mounting locations
and methods vary, you will need to obtain an antenna mount
to install the GPS 17. The receiver base fits a standard 1-
inch, 14 threads-per-inch marine mount. Check with your
Garmin dealer or a marine supply retailer for this item.
• On/Off switch (optional)— Power to the receiver
may be controlled by an on/off switch, such as an accessory
switch on the control console. Check with your Garmin
dealer or a marine/electric supply retailer for this item.
It is recommended that the system be temporarily
hooked up with the wiring and the unit placed at the desired
installation location. Then, check operation with potential
interfering equipment turned on and off. (For example, other
electronic equipment, fan motors, engine ignition, alterna-
tors, generators, radars, and VHF radio transmissions can be
sources of interference.)
Position the receiver so that the clearest possible view
of the sky and horizon in all directions is obtained. Avoid
mounting the antenna next to large areas of conductive
material (metal, aluminum, etc.) as this may cause poor
signal reception. It is not recommended that the GPS 17 be
mounted high on a mast, as the top of the mast travels more
than the boat. The unit will provide more stable readings if
it is located nearer to the water level. The GPS 17 is supplied
with a 30 feet power/data cable. When routing the wiring to
the GPS 17, avoid routing the cable near the vessel’s alterna-
tor or ignition system components or parallel to other power
lines.

Note: As a general rule, mount
the receiver at least three
feet from all other antennas
and the vessel’s electrical
system components
(alternator/ignition system).
