GPSMAP 1643xsv: The Ultimate 16-Inch Marine Command Center for Anglers and Sailors

Elevate your on-water adventures with the Garmin GPSMAP 1643xsv, a powerhouse 16-inch chartplotter that fuses cutting-edge GPS navigation, advanced fishfinding, and seamless system integration into one sleek, helm-ready unit. Designed for the serious mariner, this combo device delivers crystal-clear situational awareness through its upgraded IPS touchscreen display, offering wide viewing angles and vibrant visuals even under direct sunlight—perfect for spotting the next big catch or plotting the ideal course.

Precision Navigation Meets Pro-Grade Sonar Preloaded with Garmin Navionics+ charts covering the U.S. and Canada, the 1643xsv provides detailed coastal and inland mapping, including high-resolution bathymetric data and auto-guidance+ pathfinding to suggest optimal routes while avoiding low bridges and shallow hazards. Built-in Wi-Fi and ANT+ connectivity let you sync with your smartphone for real-time weather overlays, smart notifications, and remote helm control via the Garmin ActiveCaptain app. For anglers, the integrated Ultra High-Definition scanning sonar—featuring SideVü and ClearVü with high-contrast color palettes—reveals fish-holding structures in stunning detail, while 1 kW CHIRP traditional sonar support ensures reliable bottom tracking down to 3,000 feet. Pair it effortlessly with compatible Garmin transducers (not included) or LiveScope sonar for live-action underwater views.

Versatile Integration for Any Vessel This all-in-one fishfinder/chartplotter shines in connected setups: integrate with up to four engines via J1939 protocols for fuel-efficient monitoring, or link to third-party devices like digital switching systems and OneHelm apps for streamlined boat management. Sailors will appreciate Garmin SailAssist tools, including laylines, race countdowns, and virtual start-line guidance, while Force trolling motor compatibility keeps you locked on prime fishing spots. With NMEA 2000 networking, expand your marine ecosystem by adding radars, autopilots, or cameras for a fully unified command experience—all manageable from nearly anywhere with app-based controls.
