July 1, 2025

Garmin, the world’s largest¹ and most innovative marine electronics manufacturer, has announced the GPSMAP® 15×3 chartplotter, providing boaters, cruisers and sailors with an ultrawide 15-inch touchscreen for a stunning high-resolution display, superior clarity and a sleek design to optimize space in the helm. With an edge-to-edge glass format that fits a wide range of dash configurations, users can enjoy the advantages of dual screens without needing two separate units, making it easier to display the data and applications they use most.  
 
“We are excited to add an ultrawide display option to our popular GPSMAP x3 chartplotter series that offers boaters and anglers a more expansive, immersive field of view. Coupled with its easy-to-use functionality, built-in mapping and superior sonar capabilities, the GPSMAP 15×3 delivers an incredible experience at the helm.” 
–Susan Lyman, Garmin Vice President of Global Consumer Sales & Marketing
 
What mariners will love about the GPSMAP 15×3:
 
·       Ultrawide display: Experience enhanced viewing clarity with the 15-inch high-resolution touchscreen that’s 74% wider than a standard 9-inch chartplotter.

·       Split-screen customization: The ultrawide display is optimized for viewing applications side by side and utilizes sidebar controls so users can easily customize and view the data they use most without switching screens.

·       Built-in sonar: Ultra High-Definition ClearVü™ and SideVü™ scanning sonars offer vivid, high-contrast color palettes to help distinguish fish from structure². Optional Panoptix™, LiveScope™ live sonar and CHIRP traditional sonar are also supported.

·       Preloaded mapping: Experience unparalleled coverage and detail with built-in Garmin Navionics+™ integrated mapping, which includes Auto Guidance+™ technology³ and a one-year plan for downloadable daily updates. Users can also add Garmin Navionics Vision+™ for premium features like high-resolution relief shading, satellite imagery and more.

·       Force® integration: When integrated with a Garmin Force trolling motor, anglers can create routes, patterns and tracks for the trolling motor to follow while they fish. From the chartplotter screen, they can also control speed, check battery life and more.

·       Seamless connectivity: Easily build an onboard marine system with compatible sonar, autopilot, radars, instruments, stereos, cameras and more by using NMEA networks or the Garmin Marine Network.

·       Engine data support: View essential engine information such as RPMs, fuel flow and more for compatible engine manufacturers.

·       Management of onboard systems: Control all boat operations on one screen. Utilize Garmin’s EmpirBus™ digital switching to control lighting, power management and more, or the OneHelm™ integrated solutions allow users to control third party systems and devices.

For simplified aftermarket and OEM installation, the GPSMAP 15×3 offers two different mounting options. A bail-mount option with inset knobs and a bracket to support the unique floating display installations, while a rear-mount option provides secure flush and flat-mount helm solutions.
 
Available now, the GPSMAP 15×3 has a suggested retail price of $4,499.99. USD. To learn more, visit www.garmin.com/marine
