Garmin GMS10 Reman Network Port Expander

The Garmin GMS10 Reman Network Port Expander (Model 010-N0351-00) is a remanufactured marine networking hub designed for anglers and boaters who run multi-display Garmin chartplotter systems. Whether you're managing a fishing vessel with multiple stations or a larger recreational boat, this network port expander solves the common problem of limited connectivity on your onboard Garmin Marine Network. It allows you to centralize sensor data, sounder feeds, and navigation displays across your entire boat without the hassle of running separate hardware.

Built around a robust 100 MB Ethernet switch, the GMS10 expander acts as a traffic hub for your integrated marine electronics, enabling you to connect multiple chartplotters, transducers, radar units, and sensors simultaneously over a single Garmin Marine Network backbone. The remanufactured unit carries the same industrial-grade reliability as new models, having passed Garmin's rigorous quality testing and rebuild standards. At just over 3 lbs, it's compact enough to mount in an engine room, electrical panel, or console cabinet without consuming valuable deck space.

This expander is ideal for serious tournament anglers, commercial fishing operations, and cruising boaters running networked sounder, GPS, and autopilot systems from the same display ecosystem. Remanufactured Garmin equipment offers proven cost savings without compromise—perfect for retrofit upgrades or expanding existing installations. The GMS10 integrates seamlessly with compatible Garmin GPSMAP and ECHOMAP series chartplotters, supporting both traditional NMEA 0183 and modern high-speed NMEA 2000 protocols for maximum flexibility and future expandability.
