The Garmin GMS 10 Network Port Expander lets you connect multiple chartplotters and sensors across the Garmin Marine Network via a robust 100 MB switch. Data transfer runs at Ethernet-like speeds — up to 10 times faster than some competing systems. Every peripheral is automatically detected the moment it's connected, making expansion as simple as plugging in a standard data cable. Built for the marine environment, all connections are fully water-resistant and sealed covers protect unused ports from moisture and corrosion.
