This listing is for a used Garmin GXM51 satellite weather and data receiver. Please note that while the GXM51 unit itself is pre-owned, the audio module, network cable, and accessories are brand new. The unit was thoroughly tested on a Garmin chartplotter to ensure its functionality, providing full confirmation that the GXM51 works as expected.

Additionally, during the testing process, we took the opportunity to update the antenna to the latest available software version provided by Garmin, ensuring optimal performance and compatibility. This makes it a great option for anyone looking to enhance their onboard weather and data experience.

Please note: Because this is a quantity listing, you will receive an item that is equal to or better in condition than the one shown in the photos. Each GXM51 antenna is individually tested with its own cable and updated to ensure consistent quality and performance across all units.

Overview:
The GXM 51 can be powered directly through the NMEA 2000 bus, so no separate power connection is required. Access more than 20 different types of weather information (including NEXRAD, lightning, wave heights, water temps and wind data) from your chartplotter screen (depending on the XM WX Satellite Weather package). Plus, with a subscription, you can use the GXM 51 to enjoy more than 170 channels of quality audio via SiriusXM Satellite Radio.
