See The Way

eTrex 20 has an enhanced 2.2 in 65K color, sunlight readable display. Durable and waterproof, eTrex 20 is built to withstand the elements. It has an upgraded interface yet retains its legendary toughness to withstand the elements – be it dust, dirt, humidity or water, none of which are a match for this storied navigator.
Go Anywhere

With an array of compatible mounts, eTrex 20 is designed for use on ATV’ s, bicycles, in boats, as a handheld or in your car. Use the auto mount capability and City Navigator NT® maps for turn-by-turn driving directions, or the rugged mount for your motorcycle or ATV. Wherever you think you might take eTrex, it has the mapping and mounts to get you there.
Go Global

The new eTrex series is the first-ever consumer-grade receivers that can track both GPS and GLONASS satellites simultaneously. GLONASS is a system developed by the Russian Federation that will be fully operational in 2012. When using GLONASS satellites, the time it takes for the receiver to “ lock on� to a position is ( on average) approximately 20 percent faster than using GPS. And when using both GPS and GLONASS, the receiver has the ability to lock on to 24 more satellites than using GPS alone.
Add Maps

With its microSD™ card slot and 1.7 GB of internal memory, eTrex 20 lets you load TOPO 24K maps and hit the trail, plug in BlueChart® g2 preloaded cards for a great day on the water or City Navigator NT® map data for turn-by-turn routing on roads ( see maps tab for compatible maps) . eTrex 20 also supports BirdsEye™ Satellite Imagery ( subscription required) , that lets you download satellite images to your device and integrate them with your maps.
Keep Your Fix

With its high-sensitivity, WAAS-enabled GPS receiver and HotFix® satellite prediction, eTrex locates your position quickly and precisely and maintains its GPS location even in heavy cover and deep canyons.
