GARMIN GXM 54 Marine Weather Receiver and Antenna Installation Guide

Important Safety Information

WARNING

The weather information provided through this product is subject to service interruptions and may contain errors, inaccuracies, or outdated information, and consequently should not be relied upon exclusively. Always use common sense while navigating, and check alternate weather information sources prior to making safetyrelated decisions. You acknowledge and agree that you shall be solely responsible for use of the weather information and all decisions taken with respect to navigating in weather. Garmin® will not be responsible for any consequences of using SiriusXM® weather information.
When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. In addition, connecting the power cable without the appropriate fuse in place voids the product warranty.

CAUTION

To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.

NOTICE

When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.

Software Update

You must update the Garmin chartplotter software when you install this device. For instructions on updating the software, see your chartplotter owner’s manual at support.garmin.com.

Antenna Mounting Considerations

You can mount the antenna on a flat surface or attach it to a standard 1 in. OD, 14 threads per inch, pipethreaded 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 .
  

• The antenna should not be mounted where it is shaded by the superstructure of the boat  , a radome antenna, or the mast.

• The antenna should not be mounted near the engine or other sources of Electromagnetic Interference (EMI)

• If a radar is present, the antenna should be mounted above the path of the radar  . If necessary, the antenna may be mounted below the path of the radar  .
  

• The antenna should not be mounted directly in the path of the radar .

• The antenna should be mounted at least 1 m (3 ft.) away from (preferably above) the path of a radar beam or a VHF radio antenna .
  

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.
3. Repeat steps 1–2 until you observe full or acceptable signal strength.
4. Permanently mount the antenna.

Surface Mounting the Antenna

If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer when the screws are tightened.
Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting Considerations, page 2).

1. Using the surface-mount bracket as your mounting template, mark the three pilot-hole locations and trace the cable-hole in the center of the bracket.

2. Set the surface-mount bracket aside. Do not drill through the bracket.
3. Drill the three 3.2 mm (1 /8 in.) pilot holes.
4. Drill the 25 mm (1 in.) cable hole in the center.
5. Use the included M4 screws to secure the surface-mount bracket to the mounting surface.
6. Route the cable through the center hole, and connect it to the antenna.
7. Verify the large gasket is in place on the bottom of the antenna, place the antenna on the surface-mount bracket, and twist it clockwise to lock it in place.
8. Secure the antenna to the mounting bracket with the included M3 screw .
9. Route the cable away from sources of electronic interference.

Mounting the Antenna with the Cable Routed Through the Pole

Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting Considerations, page 2).

1. Position a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included) in the selected location, and mark the approximate center of the pole.

2. Drill a hole using a 19 mm (3 /4 in.) drill bit for the cable to pass through.

3. Fasten the pole to the boat.

4. Thread the pole-mount adapter onto the pole. Do not overtighten the adapter.

5. Route the cable through the pole and connect it to the antenna.

6. Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place.

7. Secure the antenna to the adapter with the included M3 set screw  .
   

8. With the antenna installed on the pole mount, fill the vertical cable slot with a marine sealant (optional).

9. Route the cable away from sources of electronic interference.

Mounting the Antenna with the Cable Routed Outside the Pole

Before you permanently mount the antenna, you must test the mounting location for correct operation (Antenna Mounting Considerations.

1. Route the cable through the pole-mount adapter , and place the cable in the vertical slot along the base of the pole-mount adapter.
2.  Screw the pole-mount adapter onto a standard 1 in. OD, 14 threads per inch, pipe-threaded pole (not included). Do not overtighten the adapter on the pole.
3. Connect the cable to the antenna.
4. Place the antenna on the pole-mount adapter and twist it clockwise to lock it in place.
5. Secure the antenna to the adapter with the included M3 set screw .
6. With the antenna installed on the pole mount, fill the remaining gap in the vertical cable slot with a marine sealant (optional).
7. Attach the pole to the boat if it is not already attached.
8. Route the cable away from sources of electronic interference.

Connection Considerations

NOTICE

If you are connecting the audio cable from the wiring harness, you must connect it to the line-in or auxiliary port on a stereo. Attempting to connect the audio cable directly to a speaker will result in poor performance, and it may cause the antenna to shut down, which might damage the antenna or the speaker.
You must connect this antenna to power and to the Garmin Marine Network to provide weather information to connected, compatible Garmin devices.
