Garmin 40ft Network Cable

The Garmin 40ft Network Cable connects chartplotters, sonar modules, radar units, and other Garmin Marine Network devices over longer runs. If your helm and your sonar module or radar are spread out across the boat, this is the cable that bridges the gap. Standard Garmin Marine Network connector on both ends.

What It Does on the Water

Garmin Marine Network cables carry data between compatible Garmin devices at up to 100 Mbps. The 40-foot length works for larger boats where the helm and electronics are farther apart, or where you need to route cable around the gunwale or through the console. Use it with the GMS10 network port expander to connect multiple devices across the network.

Compatible with all Garmin Marine Network devices including ECHOMAP, GPSMAP, GMR radar units, and the GMS10 port expander.
