The GMS 10 is a network port expander that allows you to connect multiple chartplotters, multi-function displays (MFDs), and sensors through the Garmin Marine Network. With its robust 100 Mb switch, it delivers fast data transfer speeds — up to 10 times faster than some competing systems. It operates with true plug-and-play simplicity, meaning all connected peripherals are automatically detected as soon as they are plugged in. Expanding your network is easy: just use the same standard data cable to add additional devices to the GMS 10 ports. Designed specifically for harsh marine environments, the GMS 10 is fully waterproof, featuring sealed connections and protective covers for unused ports to keep out moisture and prevent corrosion.
