INSTALLATION
INSTRUCTIONS
Important Safety Information
To avoid possible personal injury, always wear safety goggles,
ear protection, and a dust mask when drilling, cutting, or
sanding.
When drilling or cutting, always check what is on the opposite
side of the surface to avoid damaging the vessel.
For the best performance and to avoid damage to your boat,
read all installation instructions before proceeding. Install the
device per these instructions. Use the appropriate fasteners,
tools, and mounts listed, which are available at most marine
dealers.
The Garmin GPS 24xd NMEA 2000 high-sensitivity GPS
®
antenna provides position information to your existing NMEA
2000 network. If your boat does not have a NMEA 2000
network, you will need to install one.

Tools Needed
• Drill
• 3.2 mm (1/8 in.) drill bit
• 19 mm (3/4 in.) drill bit for a pole-mount cable-hole
• 1 in. (25 mm) hole saw for a surface-mount cable-hole
• Countersink bit for mounting on fiberglass
• Screws for under-deck mounting
• Screwdriver, appropriate for the screw type
• Marine sealant (optional)
• Additional NMEA 2000 network components as needed
Mounting the Antenna
Antenna Mounting Considerations
Do not install or store the antenna near strong magnets,
including speakers. A strong magnetic field can damage the
antenna.
You can mount the antenna on a flat surface or attach it to a
standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not
included). You can route the cable outside of the pole or through
the pole. For best performance, consider these guidelines when
selecting the antenna mounting location.
• To ensure the best reception, the antenna should be
mounted in a location that has a clear, unobstructed view of
the sky in all directions

CAUTION
NOTICE
CAUTION
.
®
• The antenna should not be mounted where it is shaded by
the superstructure of the boat
mast.
• The antenna should not be mounted near the engine or other
sources of Electromagnetic Interference (EMI)
• The antenna should not be mounted near known ferrous
metal objects such as a toolbox or compass.
• A handheld compass should be used to test for magnetic
interference in the area where the antenna is to be mounted.
Your boat, motors, and devices must be on during the test.
If the needle on the handheld compass moves when you hold
it where you intend to mount the antenna, magnetic
interference is present. You must choose another location
and test again.
• Mounting screws are provided with the antenna. If you use
mounting hardware other than the provided screws, the
hardware must be made of quality stainless steel or brass
material to avoid magnetic interference with the antenna.
NOTE: Test all mounting hardware with a handheld compass
to make sure no magnetic fields are present in the hardware.
• If a radar is present, the antenna should be mounted above
the path of the radar
mounted below the path of the radar
• The antenna should not be mounted directly in the path of the
radar .
• The antenna should not be mounted within 1 m (3 ft.) of a
VHF radio antenna or the path of a radar
Testing the Mounting Location
1
Temporarily secure the antenna in the preferred mounting
location and test it for correct operation.
2
If you experience interference with other electronics, move
the antenna to a different location, and test it again.
