Garmin GPSMAP923 9in Plotter delivers precision navigation and effortless control for serious mariners. Featuring a worldwide basemap, this high‑performance chartplotter helps you navigate with confidence, wherever your voyage takes you.
Designed to be faster and easier to read, the GPSMAP923 packs 50% more display pixels and nearly double the processing power of previous 9" GPSMAP models. The crisp touchscreen uses an IPS, high‑resolution, edge‑to‑edge glass display in a slimline form factor that fits a wider range of dash configurations while delivering superb sunlight readability and visibility from any angle.
Build your marine system with seamless network connectivity. The GPSMAP923 lets you:
- Share maps, user data, radar and IP camera video across compatible Garmin devices, enhancing situational awareness on every screen.
- Connect to autopilots, digital switching, weather, Fusion‑Link audio, VHF, AIS and more from a single interface.
- Pair with OneChart, Garmin Helm digital switching, and the Quickdraw Community data for a smarter, more connected voyage.
Take the guesswork out of sailing with clear laylines, race start line guidance, enhanced wind rose, and wind data fields, plus tide/current/time slider, wind angle, set and drift, wind speed and more. The plotter also supports optional premium charts with Navionics data and Auto Guidance technology for effortless routing.
Compatibility and engine integration are at the core of the GPSMAP923. It can connect with some of your favorite devices—such as quatix watches, gWind wireless transducers, GNX Wind instruments, and wireless remotes—and, importantly, it can connect to select Yamaha engines for integrated control and monitoring.
Optional sonar and transducer capabilities expand your view below the surface. Pair with Panoptix PS51 (transducer sold separately) with FrontVü scanning sonar to see submerged obstacles up to 300 feet away in real time, helping you navigate safely as you approach structure or targets.
