Unlock Advanced Mapping for Every Journey
Right out of the box, the GPSMAP 942 Plus comes loaded with BlueChart g3 coastal charts and LakeVü g3 inland maps, blending Garmin's proprietary data with Navionics expertise. These charts offer unparalleled detail, including high-resolution relief shading for spotting underwater contours and Auto Guidance+ technology that suggests safe boating paths, factoring in your vessel's draft and beam.

- Quickdraw Contours to create personalized HD maps in real-time.
Build a Connected Marine Ecosystem
Integration is at the heart of the GPSMAP 942 Plus. Leverage the Garmin Marine Network to share user data, maps, radar overlays, and IP camera feeds across multiple screens. Connect effortlessly to NMEA 2000 and NMEA 0183 networks for autopilots, VHF radios, AIS receivers, digital switching like EmpirBus, and even engine data from Yamaha and other J1939-compatible motors. Built-in Wi-Fi pairs with the Garmin ActiveCaptain app, letting you manage updates, receive smart notifications, and access community-sourced charts from anywhere on shore.
Pair with third-party favorites: FUSION-Link audio for onboard entertainment, quatix watches for wrist-based control, or gWind transducers for precise wind data. Add Panoptix LiveScope sonar (transducer separate) to peer 360 degrees around your boat in real-time, revolutionizing fishing and docking.
Sail Smarter with Built-In Racing Tools
For sailors, the GPSMAP 942 Plus shines with SailAssist features that eliminate guesswork. Visualize laylines, race start lines with synchronized countdowns, wind roses, true wind angles, set/drift indicators, and tide/current sliders directly on-screen. Heading lines, course-over-ground vectors, and wind speed fields provide tactical edges during regattas or casual cruises. These tools, refined through feedback from competitive sailors, help optimize sail trim and course decisions on the fly.
Rugged Design Meets Cutting-Edge Performance
Crafted for the marine environment, this chartplotter boasts an IPX7 water rating, polarized lens support for glare reduction, and a compact footprint that fits bail or flush mounts. The 10 Hz GPS/GLONASS receiver delivers smooth tracking, while dual-frequency sonar compatibility (with black box add-on) supports CHIRP, ClearVü, and SideVü for detailed underwater views.
