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 BlueNet™ or Garmin® Marine Network to provide weather information to connected, compatible Garmin devices.

For more information about the differences between Garmin BlueNet network technology and the legacy Garmin Marine Network, go to garmin.com/manuals/bluenet.

Description

Notes

1

Antenna

2

Ignition or in-line switch (not included)

You should connect the power and audio module to the battery through the ignition switch or through an additional in-line switch (not included). Connecting the harness directly to the battery may drain the battery.

3

Antenna cable

This cable connects the antenna to the power audio module, and is 6 m (20 ft.) long.

This cable is the same as a standard Garmin BlueNet cable (small connector on both ends), and additional lengths are available from your Garmin dealer or garmin.com if needed.

4

9 to 32 Vdc power source

5

Power and audio module

You should install the module in a location with access to power, the installed antenna, and a Garmin Marine Network device.

You can secure the module to existing cabling or a structure using zip ties (not included), or you can secure it to a bulkhead using the included screws.

6

Garmin BlueNet or Garmin Marine network device

If you are connecting this cable to a legacy Garmin Marine Network, you can connect it to any open port on a Garmin chartplotter or GMS™ 10 network port expander.

If you are connecting this cable to a Garmin BlueNet network, you should remove the adapter cable and connect it to any open Garmin BlueNet network port on a Garmin chartplotter or Garmin BlueNet 20 switch.

7

Audio out cable

Connects to the line-in or auxiliary port on a stereo to listen to SiriusXM® stations.

You can extend this cable using a standard RCA cable if necessary. Extension-cable connections should be made in a protected area that is not exposed to water.
