Explore at the edges.

As fun as it is to pull a weathered map from the depths of a pannier and painstakingly plot the route, it's even better to not have to worry about getting lost along the way. Whether you're looking to get adventurous on your daily commute or planning epic training miles ahead of a double century, the Garmin Edge Explore 820 Bike Computer is there to guide you to your destination. The Edge Explore 820 lets you stop to take in the scenery without the stress of also trying to figure out where you're supposed to turn next.

The Explore 820 effectively replaces the Edge Touring and Touring Plus computers in Garmin's line. Its full touchscreen is a welcome and user-friendly upgrade from its predecessors' mixed button/touchscreen design, but the mapping options are what really set this computer apart. It comes with a preloaded Garmin Cycle Map and internal memory for adding more maps if needed, and it uses this library to let you precisely plan your routes, provide round-trip direction, and offer up audio prompts via Garmin Connect Mobile so you can keep tabs on your speed and heart rate without taking your eyes off the road and scenery ahead.

In case you're looking for a little travel inspiration, Garmin has ensured that you're able to peruse rides and routes that others have completed via your Garmin Connect or Garmin Adventures account online. After you've found a route that you want to try, you're able to download it to your Explore 820 for your next ride. Additionally, you can customize existing routes or create new ones before you download them to your device. Of course, both of these programs allow you to relive and share your ride with friends, family, or fellow Garmin users.

The Edge Explore 820 features ANT+ connectivity to pair with heart rate monitors or other metric-gathering devices, though it's important to note that the Explore 820 is not compatible with power meters. It performs all the basic computer functions—speed, trip time, trip distance, odometer—and the GPS and GLONASS compatibility keeps you located no matter where your ride takes you. The Edge Explore 820 automatically uploads to Garmin Connect, syncs with smart phones for notifications, and displays weather information so you're never out of the loop or surprised by changing conditions mid-ride.

Device keeps getting worse

  • Familiarity: I've put it through the wringer

I purchased this device in October. From day 1, it had bad touchscreen issues, maybe one in three touches would actually go through on the device. I didn't return it because the official word from Garmin was that this was a software problem that would be fixed in the next update.

Fast forward 5 major version firmware updates, and the touchscreen performance is just as bad, if not worse. Even trying to switch screens with a big swipe tends to not work 50-70% of the time. In addition, the battery life seems to be getting worse as the firmware gains complexity.

I've contacted Garmin about the touchscreen issues, and given their support response it seems this is the expected level of accuracy for the 820.

If I were buying a new head unit today, I would not buy an 820. Instead, the Wahoo ELEMNT Bolt is a compelling option that will give you fewer headaches both on and off the bike.

Does this unit have a function that will allow the user to mark their start location (trailhead or Truck) and if you get lost on your ride, will it tell you what direction to go and how far to get back to the start location? like a garmin Etrex...

Hey Tony,

It does have the functionality to mark a location and get you back to that location. I am shooting you an email so that we can chat more about this.
