GPSMAP 8612 12-inch Plotter with US & Canada Navionics+ charts is a premier navigation hub built for serious boaters who demand clarity, speed, and total cockpit control. The 12-inch full HD IPS touchscreen delivers wider viewing angles, exceptional detail, and superb daylight readability—even with polarized sunglasses.
Designed for a modern, glass-helm aesthetic, this chartplotter supports multiple displays that can be flat mounted edge-to-edge for a sleek, uninterrupted cockpit or mounted flush for a clean, integrated look.
Seamless connectivity and network integration: Fully network capable with NMEA 2000® and the Garmin Marine Network, you can easily build a complete marine system—from sonar, radar, and autopilots to instruments, cameras, and multimedia. ANT® connectivity and Wi‑Fi® networking let you pair with compatible quatix® smartwatches, the gWind™ Wireless 2 wind sensor, and more. The exclusive OneHelm™ feature puts many third‑party devices under one control screen for effortless operation.
Precise charts and planning tools: Preloaded Garmin Navionics+™ coastal charts and inland mapping include Auto Guidance+™ technology to assist planning and routing (Auto Guidance+ is for planning purposes only and does not replace safe navigation operations). Optional Garmin Navionics Vision+™ premium map content expands your map data for even more detail and capabilities.
Advanced engine and sonar compatibility: See RPMs, fuel flow, temperature, trim, and more for up to four Mercury® engines via the SmartCraft® Connect gateway. Pair with Panoptix™ PS51 transducer with FrontVü™ forward-looking sonar to avoid grounding and maintain situational awareness in shallow or complex waters.
Smart controls and race-ready features: Built-in SmartMode™ station controls offer one-touch presets for docking, cruising, fishing, and anchoring. Built-in Garmin SailAssist™ provides data, displays, and prerace guidance to help you gain a competitive edge on the water.
App and charting ecosystem: Use built-in Wi‑Fi networking to pair with the free ActiveCaptain® smartphone app for OneChart™ access, smart notifications, Garmin Quickdraw™ Community data, and more. Dual microSD™ card slots on the back of the unit support ActiveCaptain® app expansion and cartography accessories for flexible map storage and updates.
