Boaters and marine professionals know the frustration of running out of ports on their chartplotter. The Garmin BlueNet™ 20 Switch solves this by seamlessly adding more connections to your Garmin BlueNet™ network. Whether you're integrating radar, sonar, cameras, or additional displays, this switch keeps your high-speed data flowing without bottlenecks. Designed for rugged marine environments, it handles vibrations, moisture, and temperature swings while maintaining reliable gigabit Ethernet speeds.
Imagine wiring up your vessel's full suite of Garmin electronics—autopilots, fishfinders, and engine data monitors—all sharing real-time info. This switch turns a limited setup into a robust, scalable system, perfect for larger boats or complex installations.
Installation is straightforward. Connect the included 2-meter BlueNet™ cable from your chartplotter's port to the switch, attach the power cable, and secure with provided mounting hardware. It's optimized for bulkhead or overhead mounting in tight console spaces. Pro tip: Plan your cable runs in advance to minimize interference and maximize signal integrity—route away from high-power lines like VHF antennas.
For best results, pair with Garmin's ecosystem of marine multifunction displays. This setup enables features like overlaying radar returns on charts or sharing sonar data across screens, enhancing situational awareness on the water.
From weekend cruisers to commercial operators, the BlueNet™ 20 Switch shines in:
Users report fewer dropped connections and smoother updates compared to generic switches, thanks to Garmin's proprietary protocols.
Everything you need arrives ready to install:
It expands available ports on your compatible Garmin chartplotter, allowing more devices to join the high-speed BlueNet™ network for shared data like charts, radar, and sensors.
It's designed for chartplotters with BlueNet™ ports, such as select GPSMAP® and chartplotter series. Check your model's specs for BlueNet™ support.
The switch adds multiple Ethernet ports specifically for BlueNet™ expansion, enabling a larger network without overwhelming the chartplotter.
Yes, its waterproof and corrosion-resistant construction makes it ideal for marine use, including open ocean conditions.
