Garmin 010-11251-90 SiriusXM Marine Weather & Audio Antenna for NMEA 2000 Chartplotters

At the helm of an offshore fishing boat, a captain glances at the GPSMAP 8612xsv and sees a storm cell building 40 miles out. With the Garmin 010-11251-90, that same screen overlays real-time NEXRAD radar, lightning strikes, and sea state data while SiriusXM satellite radio plays through the cabin speakers.
