Enhance Your Marine Navigation with Seamless SD Card Access

Imagine cruising on open waters without constantly fumbling at your chartplotter’s dashboard for map updates or data transfers. The Garmin Card Reader changes that by bringing dual SD card slots right to your fingertips, wherever convenient on your vessel. Designed for boaters who value efficiency, this compact unit mounts remotely—horizontally or vertically—thanks to its versatile hardware and a clever waterproof magnetic door that snaps shut securely against splashes and spray.

Whether you’re swapping nautical charts, backing up sonar logs, or loading fresh fishing hotspots, multiple units can network together for even more access points. It’s a game-changer for larger boats where the helm station feels miles from ideal spots like the helm console or companionway.

Built Tough for Harsh Marine Environments

Crafted from high-impact plastic with full gasketing, this reader meets IPX7 waterproof standards, surviving immersion up to 1 meter for 30 minutes. It thrives in temperatures from -15°C to 70°C (-5°F to 158°F), making it reliable from foggy dawns to scorching afternoons. Power it via 10-35 Vdc systems with low draw—typically 80 mA at 12 Vdc—ensuring it won’t strain your boat’s electrical setup. A 7.5A fast-acting fuse adds peace of mind.

• Compact Size: 2 1/8″ x 4 7/8″ x 3 3/16″ (54.3 x 124.1 x 81.2 mm) – fits tight spaces.
• Lightweight: Just 6.3 oz (178.6 g) for easy handling.
• Compass Safe: Maintains 36″ (915 mm) distance to avoid interference.
• Power Efficiency: Max 2.4 W at 10 Vdc, with peak 240 mA draw at 12 Vdc.

Effortless Installation and Setup

Getting started is straightforward. Use the included mounting hardware to secure it in your chosen spot, connect the 6 ft network cable to your Garmin marine display, and hook up the power cable to your system’s bus. No complex wiring—just plug and play with compatible Garmin chartplotters and multifunction displays. For boats with multiple stations, daisy-chain readers via the network for shared access, reducing clutter and improving workflow during long voyages.

Pro tip: Position it near high-traffic areas like near throttles or chart tables to minimize disruptions while underway. Regular checks on the magnetic door seal keep it performing flawlessly season after season.

Real-World Benefits for Boaters and Anglers

Captains rave about how this frees up dash real estate on smaller consoles, while offshore anglers appreciate quick swaps for region-specific charts without powering down. It’s ideal for liveaboard setups too—update software or routes from the galley instead of the flybridge. By centralizing access, you cut down on errors like inserting cards in rough seas, keeping your focus on navigation and safety.

In competitive fishing tournaments, where every second counts, remote access means faster data pulls without leaving the rod holders. Pair it with Garmin’s BlueChart g3 or LakeVü maps for top-tier performance, enhancing situational awareness across inland lakes, coastal runs, or bluewater passages.
