The Garmin GXM™ 53 SiriusXM® Satellite Weather and Audio Antenna (010-01734-00) is an integrated receiver and high-gain antenna system designed to deliver real-time weather data and satellite entertainment directly to compatible Garmin GPSMAP® chartplotters. Connecting seamlessly via the Garmin Marine Network, the GXM 53 receives high-resolution SiriusXM Marine weather information—including NEXRAD radar, storm tracking, surface pressure, sea surface temperatures, wind speed/direction, wave height, and marine warnings—giving mariners crucial situational awareness for safer navigation.

Constructed with a fully gasketed, IPX7 waterproof housing, the unit is built to withstand harsh marine environments and includes an external Power and Audio Module for splitting audio output to an onboard stereo system. High-bandwidth Ethernet connectivity allows fast data transfer and power delivery over a single connection. The antenna comes complete with versatile mounting hardware for surface, pole, or under-deck installation, making it a reliable solution for maintaining optimal reception even on the fringes of SiriusXM coverage.
