Garmin GPS Map 420
The GPSMAP 420 is a sleek, space-saving Chartplotter that features an ultra-bright 4inch QVGA display; built-in, satellite-enhanced worldwide base map and simplified user operation. The 420 also has an SD™ card slot so you can add additional features with the optional BlueChart® g2 Vision card.
View Satellite-enhanced Maps
The 420’s base map contains worldwide satellite images in place of more traditional maps, and its SD card slot makes it easy to add additional maps without connecting to a computer. With fewer keys and a simple, intuitive interface, the 420 makes navigating your way through the water easy.
Where applicable, the sounder version, GPSMAP 420s, comes with a powerful dual-frequency transducer that clearly paints depth contours, fish targets and structure whether you’re fishing in freshwater or off the coast. The 420 and 420s are also CANet™ compatible, so you can share sounder data with another Chartplotter on your boat.
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.
MarinerEye view and FishEye view provide 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.
