With its sleek design, powerful processing, and upgraded IPS display, the Garmin® GPSMAP® 1643xsv 16" Chartplotter with Sonar and Garmin Navionics+™ Mapping integrates seamlessly into your Garmin marine system. This powerhouse Garmin chartplotter brings built-in Ultra High-Definition SideVü™ and ClearVü™ scanning sonars with vivid, high-contrast color palettes to help distinguish fish from structure. Pair with Panoptix™ or LiveScope™ easy-to-interpret live sonar (transducer not included) to see all around your boat in real time. The high-resolution 16" IPS display offers improved sunlight readability and visibility from any angle. Experience unparalleled coverage and detail with built-in Garmin Navionics+ integrated coastal and inland mapping that includes Auto Guidance+™ technology. Get support and integration for your Force trolling motor (not included) to gain complete control while you fish. Sail and navigate with ease with SailAssist™ features. View laylines, race start line guidance, enhanced wind rose, heading and course-over-ground lines, true wind data fields and tide/current/time slider, wind angle, set and drift, wind speed, and more. Use the polar table to see key data, including how fast you should go at a certain wind angle and speed — so you know whether you need to adjust sail trim. If you have multiple compatible Garmin devices on your boat, you can share information among them, such as maps, user data, radar, IP camera video, and more. Connect to compatible autopilots, digital switching, weather, the Fusion audio system, media, VHF, AIS, and more from 1 screen. Built-in Wi-Fi® connectivity pairs with the free all-in-1 mobile ActiveCaptain app for access to the OneChart™ feature, smart notifications, software updates, Helm app, Garmin Quickdraw™ Community data, and more. Integrated ANT® technology lets you connect with some of your favorite devices, such as quatix® marine watches, gWind™ Wireless 2 transducers, GNX™ Wind marine instruments, and wireless remote controls. You can connect your chartplotter to different engines, including select Yamaha® engines, and get engine data right on your display. The OneHelm feature brings together all the operations and capabilities of select third-party devices, such as EmpirBus™ digital switching, on 1 screen. Pair your inReach satellite communicator (not included) to your chartplotter, and type custom messages by using the display's on-screen keyboard. Access your contact list, or enter an email, inReach address, or phone number. You can also group messages by conversation for a texting-like appearance. The Garmin 1643sxv gives you the most dynamic and easy-to-use multifunction display you've ever experienced.
