Garmin GPSMAP 521 Chartplotter/Fish Finder Parts
Product Description:
The GPSMAP 521 is a compact chartplotter that features an ultra-bright 5” 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 GPSMAP 521 also
accepts BlueChart® g2 Vision cards for added features and functionality such as high-resolution
satellite imagery, 3-D views and Auto Guidance technology.
View Satellite-enhanced Worldwide Basemap

The GPSMAP 521 basemap contains worldwide satellite images in place of traditional maps. The
GPSMAP 521 also comes standard with a high-sensitivity GPS receiver for superior satellite
tracking and quicker acquisition times. In addition, the GPSMAP 521 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.
