GPSMAP 547 allows for easy visibility, day or night. Whether it is flat, flush or swivel-mounted, it will be the focal point of your helm. It includes our hallmark user-friendly interface as well as U.S. coastal and inland mapping.
With the integration of a 10Hz GPS/GLONASS receiver, the 547 refreshes position and heading up to 10 times per second. It displays constant and fluid on-screen location and proves to be incredibly accurate when marking and navigating to any one of 5,000 user-created waypoints.
Built-in wireless connectivity allows you to connect to and access marine-specific apps via smartphone or tablet.

View and Control Your Device from a Smartphone or Tablet
Garmin Helm™ allows you to view and control your compatible Garmin chartplotter from an iPhone® or iPad® or phone, or tablet using Android™ — while providing enhanced situational awareness for the mariner. Easily switch between portrait and landscape mode to accommodate mounting preferences. Using your iPhone or iPad, you can even record a movie of your chartplotter screen to share with friends and family. Download from the App Store™ or Google Play™ today.
Get Your Apple® Device Onboard with BlueChart® Mobile
With BlueChart Mobile, a free app downloaded from the App Store, you can plan marine routes on your iPad or iPhone then wirelessly transfer them to your boat’s compatible networked Garmin chartplotter. Even if you don’t have a Garmin chartplotter, you can still take advantage of the tremendous features of BlueChart on your Apple device.
Enhanced Auto Guidance
Just enter the location where you want to go and patented Garmin Auto Guidance² technology instantly searches through relevant charts to create a virtual pathway on the display that helps you avoid low bridges, shallow water and other charted obstructions en route.
Better still, with enhanced Version 2.0, you now have access to even more features and capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. You can easily review hazard points along your calculated path. And you can even engage your compatible Garmin autopilot to follow the Auto Guidance route, automatically. Other 2.0 enhancements give you the ability to calculate arrival times at any point on your route (great for timing arrivals to correspond with bridge openings and other time-critical events). Better still, you can now save your plotted Auto Guidance paths for future navigation by backing them up on an SD™ card with your BlueChart® g2 Vision® or Lake Vü™ HD Ultra cartography¹.
GPX Waypoints Transfer
If you have waypoints, tracks or frequently used routes stored on another manufacturer’s GPS product – or on a Garmin handheld device – now it’s easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken “no waypoint left behind” to a whole new level of trade-up convenience.
Create your own HD maps
Quickdraw Contours is a free, easy-to-use software feature already installed on your compatible Garmin combo. It instantly creates your own personalized HD fishing maps with 1-foot contours. Tailor them to fit your needs. They are your maps — you own them. Keep the data to yourself, or share it with the Quickdraw Community on Garmin Connect™. There’s no special surveying expertise required. You just fish while it creates maps.

Use with any of the following sonar transducers: Garmin Panoptix™, HD-ID™ traditional, CHIRP-enabled, Garmin ClearVü™ or NMEA 2000®-compatible depth. Have more than 1 sonar device installed onboard? Quickdraw Contours automatically selects the most capable sonar device to provide the very best results for you!
