Manufacturer Description

The Garmin

GPSMAP 421

is a compact chartplotter that features an ultra-bright 4” QVGA color display along with an improved high-speed digital design for increased map drawing and panning speeds. It’s ready to go with a built-in, satellite-enhanced worldwide basemap and an easy-to-use interface designed to help you navigate the open waters with ease. The Garmin GPSMAP 421 also accepts BlueChart® g2 Vision cards for added features and functionality such as high-resolution satellite imagery, 3D views and Auto Guidance technology.

View Satellite-enhanced Worldwide Basemap


The Garmin GPSMAP 421 basemap contains worldwide satellite images in place of traditional maps. The Garmin GPSMAP 421 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the Garmin GPSMAP 421 can receive U.S. graphical weather data via optional GXM 51 satellite receiver/antenna. And with an SD card slot, it’s easy to add additional maps without connecting to a computer.

Add Sonar


Where applicable, the sounder version, the Garmin GPSMAP 421s comes with a powerful dual-frequency transducer that clearly illustrates depth contours, fish targets and structures whether you’re fishing in freshwater or off the coast. The Garmin GPSMAP 421 and Garmin GPSMAP 421s are also NMEA 2000-certified for easy connectivity with sensors, instruments and future marine offerings.

Add Extras with BlueChart g2 Vision


With the optional BlueChart g2 Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.
  • 3D Mariner’s and Fish Eye view provides you with a 3-dimensional perspective of map information, both above and below the waterline
  • High-resolution satellite images and aerial photographs help you orient yourself in unfamiliar areas
  • Auto Guidance technology searches through all relevant charts to create a route you can actually follow — one that avoids obstacles, shallow water, buoys and other obstructions
