View Satellite-enhanced Worldwide Basemap

The GPSMAP 421 basemap contains worldwide satellite images in place of traditional maps. The GPSMAP 421 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the 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.
