No Wind Data

Wired and Wireless Wind Instruments

Garmin has both wired and wireless wind transducers. The wired gWind™ transducers use a GND 10 box to transmit wind data through NMEA 2000 to a chartplotter and / or to a GNX™ Wind instrument. The gWind™ Wireless transducers pair with either a single chartplotter or a GNX™ Wind instrument which then shares that data via the NMEA 2000 network to other devices. For discontinued models of gWind™ transducers see Related Content.

Note: When troubleshooting the wind sensor set wind to display as apparent wind angle/speed (AWA/AWS).

Basic Inspection and Troubleshooting of the Wind Transducer

Inspect that the wind sensor is freely moving in the wind
Inspect the gWind™ transducer and mount for damage. Replace if broken
Remove any obstructions found
Inspect any cable connections related to the wind sensor and GNX™ Wind instrument / chartplotter to ensure that there are no loose or chaffed wires or connectors
Power cycle the display if wirelessly paired to GNX™ Wind instrument or chartplotter
Power cycle the NMEA 2000 Network
Ensure the System Software is up to date
If the wind transducer is a wireless model, clean the solar panel and allow to charge for 5 hours or try replacing the battery: gWind™ Wireless 2 Replacement Batteries

Wired gWind™ Transducer

Check the GND 10 Status lights. There are three status lights, one status light next to each of the ports labeled for NMEA 2000, Nexus, and the USB.
- See GND 10 Status or Blink Codes for more information blink codes and steps to perform to resolve the issue.
- If there is no NMEA 2000 status light, see NMEA 2000 Troubleshooting on Garmin Marine Devices
- If the Nexus port has no lights or is not transmitting data, see GND 10 Nexus Status Light is Not Flashing Green
Verify the GNX™ Wind instrument wireless connection is OFF if no data appears on the GNX™ Wind instrument
- Press > Press until 4.0 SENSE appears > Press > if ON press and ON will blink > Press and OFF will display > Press to accept the choice

gWind™ Wireless 2 Transducer

The gWind™ Wireless 2 connects wirelessly to a compatible chartplotter or a GNX™ Wind instrument and is identified by the blue support shaft.

- Check for environmental sources that create issues for the wireless connection
  - The gWind™ Wireless 2 wind sensor maximum distance is 50ft away from the paired device
  - Lacking a clear line-of-sight between the devices
    - Obstructions, interior mounting locations, Biminis, fiberglass, metal, wood, carbon fiber, Kevlar, sails, masts, booms, rigging, and Instrument pods can have adverse effect to signal strength
  - Disruption by VHF, cell phone, other Wi-Fi systems, and electromagnetic interference

If no wind data on a GNX™ Wind instrument

- Ensure the max distance from the gWind™ Wireless 2 to the GNX™ Wind Instrument is less than fifty feet
- There is an unobstructed line-of-sight between the gWind™ Wireless 2 transducer and the GNX Wind instrument
- Verify the GNX™ Wind instrument wireless connection is on
  - If the wireless antenna symbol is missing from inside the wind rose on the GNX Wind, turn wireless feature to on:
    
    Press > Press until 4.0 SENSE appears > Press > if OFF press and OFF will blink > Press and ON will display > Press to accept the choice
- If a battery was replaced in the gWind™ Wireless 2 transducer or the gWind™ Wireless 2 transducer itself was replaced ensure the wireless pairing is set to on within the GNX™ Wind Instrument and power cycle the GNX™ Wind Instrument to re-pair devices
- Ensure power is coming from the NMEA 2000 to the GNX™ Wind instrument : [[--ContentED.656KiuIo733b27xQgmLBy7||NMEA 2000 Troubleshooting on Garmin Marine Devices||KM1008936||FAQ--]

Note : The RSSI measures the wireless signal strength from the gWind™ Wireless 2 transducer to the GNX™ Wind instrument and cannot measure between the gWind™ Wireless 2 transducers and the chartplotter.

Check the RSSI strength

If the wireless symbol displays but no wind data is showing check the wireless RSSI signal strength found under menu item 4.3 SENS Configuration Settings.

The RSSI ranges between (1-100) the higher the number the better the signal strength:

1. - - Optimal number is 70
    - Average number is 40
    - Anything lower than 25, is considered insufficient signal strength

If RSSI is below 25 or above and wind data is not present or not accurate:

1. - - Look for and remove items that disrupt the wireless signal
      - VHF, cell phone, cell tower signals, Wi-Fi, and electromagnetic interference
    - Power cycle the GNX Wind - pair the gWind™ Wireless 2 and check RSSI levels
    - Power cycle the NMEA 2000 system - pair the gWind™ Wireless 2 and check RSSI levels
    - Remove the gWind™ Wireless 2 transducer from the mount and bring it to within 10ft of GNX™ Wind instrument - pair the gWind™ Wireless 2
      - Continue to monitor the wind information and RSSI signal strength while slowly move the gWind™ Wireless 2 transducer away from the GNX™ wind instrument (Do not exceed fifty feet of separation and maintain a clear line of sight between the devices

No Wind Data on a Compatible Chartplotter

- Check the distance and line-of-sight for obstructions between the chartplotter and gWind™ Wireless 2 transducer
- If not paired to the GNX™ Wind instrument, verify the chartplotter is paired to the gWind™ Wireless 2 transducer
- If the gWind™ Wireless 2 transducer is paired to the GNX™ Wind instrument, verify the GNX™ Wind instrument shows on the chartplotter NMEA 2000 device list
  - NMEA 2000 Troubleshooting on Garmin Marine Devices
- Power cycle the chartplotter
