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.
Key Features for Superior Performance
High-Speed Connectivity: Supports Gigabit Ethernet to ensure low-latency data transfer between compatible Garmin devices.
Plug-and-Play Simplicity: No complex configuration needed—just connect and go, leveraging Garmin’s intuitive BlueNet™ architecture.
Marine-Tough Build: IPX7 waterproof rating and corrosion-resistant materials stand up to saltwater exposure and harsh conditions.
Scalable Design: Stack multiple switches to build expansive networks for professional charters, fishing vessels, or superyachts.
Efficient Power Management: Low draw keeps your boat’s electrical system balanced, even with multiple peripherals.
Simple Setup for Quick Expansion
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.
