Garmin GXM™ 53

This weather receiver/antenna combo delivers the detailed weather info you need to your Garmin chartplotter. With outstanding signal performance and a rugged design, the GXM 53 keeps you up-to-date on NEXRAD, lightning, water temperatures, wind and wave current conditions, and forecast data even when you're miles offshore. The GXM 53 connects to the Garmin Marine Network and sends your chartplotter all the weather news you need. An Ethernet connection means you get high-bandwidth data transfer through a single cable, and you can also access your favorite SiriusXM satellite radio stations (subscription required). Whether you choose to mount it on a surface or on a pole, the GXM 53 is easy to install on your boat. And if you have an older GXM 52 model, upgrading is easy, since they use the same mount.
