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
professional assistance.
The following additional items are needed or optional
to complete the installation of your GBR 23:
• Antenna mount—
Since antenna mounting
locations and methods vary, you will need to obtain
an antenna mount to install the GBR 23. The
receiver base fits a standard 1-inch, 14 threads per
inch mount. Check with your GARMIN dealer or a
marine supply company 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 company for this item.
• Fuse or cucuit breaker (optional)—
It is
recommended to install a 2-6 Amp slow response fuse
or circuit breaker to protect the curcuit that the
GBR 23 will be attached to.
• GARMIN 60’ Power/Data Cable
— For cable
installation lengths greater than 30’.(010-10284-00)
It is recommended that the system be temporarily
hooked up with the wiring and unit placement
approximating at the desired final installation. Then, check
operation with potential local interfering equipment turned
on and off. For example, other electronic equipment, fan
motors, engine ignition, alternators, generators, radars and
VHF radio transmissions can be sources of interference.
Position the receiver so that the clearest possible view
of the 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. The GBR 23 is supplied with a 30 feet power/
data cable. When routing the wiring to the GBR 23, avoid
routing the cable near the vessel’s alternator 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).
