Garmin Second Mounting Station f/GPSMAP® 500 Series — Product description

Enhance Your Boating Setup with the Garmin Second Mounting Station

Picture this: you're out on the water, navigating tricky channels or tracking fish in real-time, but your primary chartplotter is tied up showing radar while you need charts front and center. That's where the Garmin Second Mounting Station shines. Designed specifically for GPSMAP 500 Series chartplotters, this bail mount lets you add a second display effortlessly, expanding your onboard electronics without cluttering your helm.

Crafted from rugged, corrosion-resistant materials in sleek black, it withstands harsh marine conditions—salt spray, UV exposure, and constant vibrations—keeping your setup secure season after season. Boaters love how it transforms a single-screen rig into a multi-function command center, boosting safety and efficiency during long hauls or competitive fishing runs.

Seamless Integration and Versatile Connectivity

  • Bail Mount Design: Quick-release knobs allow for easy swivel and removal, perfect for storage or trailering your vessel.
  • Power and Data Ready: Comes complete with a wiring harness that powers your chartplotter and links to NMEA 0183 networks, CANet devices, or transducers for sonar data.
  • Compact Footprint: Single-unit design fits tight spaces on consoles, bulkheads, or custom dash panels.

This station isn't just a bracket—it's a hub that simplifies expanding your Garmin ecosystem. Connect multiple sensors for deeper water insights, overlay radar on one screen while plotting courses on another, or mirror displays for crew visibility.

Perfect Fit for GPSMAP 500 Series Chartplotters

Engineered for precision compatibility with models like the GPSMAP 520, 521, 525, 520s, 521s, and 525s. These chartplotters are favorites among coastal cruisers and offshore adventurers for their crisp sunlight-readable screens and robust mapping. Adding a second station means no compromises: share data across units for redundancy on critical voyages.

Effortless Installation Tips for DIY Boaters

  1. Prep Your Surface: Clean and dry the mounting area; use marine-grade sealant around screw holes for waterproofing.
  2. Position Strategically: Align for optimal viewing angles—typically 10-15 degrees tilt for standing operation.
  3. Wire It Up: Route the included harness through existing conduits; connect power (12V DC), ground, and data lines matching Garmin's color-coded standards.
  4. Test Thoroughly: Power on, verify swivel action, and simulate network data flow before hitting open water.
  5. Secure Loose Ends: Zip-tie cables and apply dielectric grease to terminals for longevity.

Most installs take under an hour with basic tools—no special skills required. For complex networks, consult your Garmin manual for pinouts.

Why Boaters Choose This Mounting Station

Beyond basic mounting, it delivers real-world value:

  • Situational Awareness: Dual screens mean charts + sonar without toggling.
  • Customizable Helm: Black finish matches most vessels; bail style suits flush or recessed installs.
  • Reliable Performance: Vibration-proof knobs and harness endure rough seas.
  • Future-Proof: Supports Garmin's evolving marine network for upgrades.

Whether upgrading a center console, outfitting a tournament bass boat, or retrofitting a classic cruiser, this station elevates your boating game.

Caring for Your Marine Electronics Mount

To maximize lifespan:

  • Rinse with fresh water after saltwater exposure.
  • Inspect knobs and screws seasonally; tighten as needed.
  • Store in a dry place during off-season.
  • Avoid high-pressure washes directly on electronics.
