Garmin Edge 820 Explore GPS Computer Head Unit

With a wealth of new features, the Garmin Edge 820 Explore GPS Computer Head Unit is a compelling package for cyclists, whether they are hitting the trails or the road. The compact 2.3-inch screen does not clutter your handlebars and its capacity touch capabilities means it works even when you are using gloves and when the screen is wet.

Keep track of your fellow group riders with the new GroupTrack feature

The Edge 820 Explore offers a massive amount of live and trackable data as well as neat new features like GroupTrack. When paired with a compatible smartphone, GroupTrack allows you to pair your device through Garmin Connect so you can keep track of your friends and ride partners out on the road. If you are looking to join up with your riding group en-route, GroupTrack allows you to easily keep track of a group of up to 50 other riders so you are never separated from the peloton.

Unparalleled data tracking and recording

Tracking and recording data from your ride has never been so simple with the Garmin Edge 820 Explore GPS Computer Head Unit. Compatibility with the Garmin Vector power pedal system (available separately) means that training with power is simple.

Connect, share and compare

Custom data fields allow you to personalise your display and suit different fields for different types of activities. Free custom data fields and apps are also available to download. When your ride is over all of this data can be fully analysed using the free Garmin Connect software, which allows you to keep track of how you perform.

Garmin Connect and a live connection to your smartphone whilst you are out on the ride also allows you to stay connected to the rest of the world with smart notifications, live tracking, social media sharing and automatic uploads to Garmin Connect and third-party services like Strava and Training Peaks.

Map your ride

Garmin remain the name synonymous with GPS mapping performance and the Edge 820 Explore offers turn-by-turn navigation and Garmin's Cycle Map provides you with routable road and bike paths as well as elevation data, points of interest and an address search. The Edge 820 Explore even has a round trip feature that selects a route appropriate to how far you want to ride and where you want to start and finish.
