The GXM 53 SiriusXM weather antenna lets you enjoy added confidence and peace of mind on the water by always having access to the most current weather conditions and forecasts. Easy-to-install and easy-to-use integrated weather receiver and antenna connects to the Garmin Marine Network to deliver highly detailed weather information directly to your compatible Garmin chartplotter. It accesses current weather information, including NEXRAD, lightning, water temperatures, wind and wave current conditions and forecast data — all of which can be viewed from your chartplotter screen. And it also provides access to SiriusXM audio stations. Additional features and upgrades are made available as Sirius XM capabilities are added. GXM 53 also recalls valid weather forecasts after a power cycle. Excellent antenna signal performance ensures you will maintain the best possible reception, even when on the fringes of SiriusXM weather coverage. Ethernet connection provides high bandwidth data transfer and power over a single cable. Provides an easy upgrade from the GXM 52 weather antenna since it uses the same mount. Full compatibility with GPSMAP 8400/8600 Series, GPSMAP 8000 Series, GPSMAP 7400/7600 Series, GPSMAP 7×2 (722/742 models)/GPSMAP 9×2 (922/942 models) and GPSMAP 10×2 (1020/1040 models)/GPSMAP 12×2 (1222/1242 models) chartplotters and chartplotter/sonar combos.
