6 Differences between the Garmin Edge 820 and 520 Bike Computers

Avatarwp-user-avatar wp-user-avatar-96 photoHere is a post that very clearly shows the differences between Garmin Edge 820 and 520. I start this post with a chart comparing all features of the Garmin Edge 820 and 520, and then I discuss the 9 key differences between them. Then I wrap it up with another chart that shows only the differences between the two bike computers, so you can see the key differences between the Garmin Edge 820 and 520 at a glance.

Note: this post was updated after posting. Garmin often brings in new features with a new unit update, and then later updates the other units with the spanking new features. This happened with the Garmin Edge 820 – it came with a lot of exciting new features, and many of these have now been shared with the Edge 520 via software updates. As a result, this post started its life as “9 Differences between the Garmin Edge 820 and 520 “, and is now “6 Differences between the Garmin Edge 820 and 520 “!

As you can see, both of these Garmin Edge bike computers have tons of features, and are in fact very similar. Both are optimized for bike training, and both are premium, rugged bike computers. Both can be paired with an impressive range of sensors. They are identical in size, although the Edge 820 is very slightly heavier. Both have color screens.

Differences between the Garmin Edge 820 and the Garmin Edge 520

There are 9 key differences between the Garmin Edge 820 and the Garmin Edge 520. This picture shows two views of the Edge 820 on the left, and two views of the Edge 520 on the right. Both have beautiful color screens and tons of shared features, including top-of-class training features

Physical Differences between the Garmin Edge 820 and the Garmin Edge 520

Difference #1: The Edge 520 does not have a touch screen, while the 820 does

Interestingly, the Edge 510 had a touch screen, and the Edge 520 reverted to buttons. Apart from that, the 520 was a massive upgrade on the 510. Garmin never said why it went back to the buttons on the 520. However, it is a known fact that some users have complained of problems with the touch screen when using Garmin Edge bike computers in the rain.

With this difference, it comes down to what you like. Personally, I find buttons easier to use when wearing gloves. However, many people prefer working with touch screens.

Difference #2: Maps on the Garmin Edge 820 vs. the Garmin Edge 520

This is another major difference. The Garmin Edge 820 comes preloaded with a Garmin Cycle Map with bike-specific navigation so it can help you with navigation. By contrast, the Edge 520 comes with the most basic of maps, which does little more than give you a rough idea of where you are (planet, country, city). Note however that you can add maps to both the 820 and the 520.

Difference #3: Navigation with the Garmin Edge 820 vs the Garmin Edge 520

The Edge 820 will give you turn-by-turn navigation instructions to a saved address or an address you have just requested. Or to a cycling-specific POI (point of interest). For example, it will alert you of an upcoming turn with a beep, and if you look at it, you will see text saying something like: “Turn right on Main St in 50 feet.” If you miss the turn, it will beep at you quite manically. However, if you ignore that, it will recalculate the route.

The Edge 520 cannot calculate routes. However, you can upload a breadcrumbs course and then follow that. When doing that, you do get turn notifications, plus an alert if you go off course. Also, thanks to software upgrades, the Garmin Edge 520 can now give you turn-by-turn navigation instructions on routes you have downloaded, as shown in this video:

Unique Features on the Garmin Edge 820

The Garmin Edge 820 is a newer bike computer, and was rolled out with a lot of new features. The Edge 820 introduced several brand new features that the Edge 520 did not have, including Group Track, Incident Alert, Battery Save Mode, and Stress Score. It was also rolled out with compatibility with Connect IQ. Thanks to software updates, the Edge 520 now has almost all of those features (except for Group Track and Battery Save Mode),

Take a look at my unboxing the Garmin Edge 820 video below, in which I show all that comes in the box (if you get the Edge 820 bundle), how to set it up, and the immediately obvious changes in appearance and menu options on this upgraded unit.

Difference #4: GroupTrack on the Garmin Edge 820

The Garmin Edge 820 was the first Garmin Edge bike computer to offer the GroupTrack feature. This lets you pair your device through Garmin Connect with other people’s compatible devices, so you can see where your riding buddies are, right on your bike computer screen. This could be handy if, for example, your wife leaves you in the dust and you need to try and catch up (yes, this has happened to me – thanks, Mrs. Average Joe Cyclist)!

Note that the other cyclists do not need to have an Edge 820 or Edge Explore 820 – they can make themselves visible to you if they have any connected, LiveTrack-compatible Edge or Forerunner. Here’s a video that shows you how the Garmin Edge GroupTrack feature works:

The Garmin Edge 820 (left) and the Garmin Edge 520 (right) are exactly the same size. Both of them took up very little space on my handlebars

Here is my Garmin Edge 820 on my handlebars. Like the Garmin Edge 520, it is slim, small, and very good looking. AND both of them can alert your significant other if you have an accident. I love that ...

Difference #5: Battery Save Mode on the Garmin Edge 820

To me, this was the most useful new feature on the Garmin Edge 820. If you are worried about losing battery power, just put the bike computer into battery save mode. The screen will blank out, but it will keep recording your ride. You can bring the screen back to life at any time. This extends the battery life by several hours. The Edge 520 does not have this feature.

Difference #6: Weight

The Garmin Edge 820 is slightly heavier than the Garmin Edge 520 – 2.4 oz (67.7 g) vs 2.1 oz (60 g). However, I am not sure if there is anyone in the world who could feel that difference. Ant Man, perhaps?

So, those are the 6 key differences between the Garmin Edge 820 and 520. There are other minor differences: for example, the 820 will store 200 hours of history, vs 180 hours on the Edge 520.

Here are all of the differences, handily summed up in this chart. This is basically the chart at the top of the post, edited down to only the rows that have differences.

CYCLING AND TRAINING FEATURES

MAPS AND NAVIGATION
Navigation?Yes - once you pick a location, it will guide you to that locationNo, it cannot figure out how to get to places. However, you can upload a breadcrumbs course and then follow that. When doing that, you do get turn notifications, plus an alert if you go off course
Turn-by-turn guidance?Yes - much like a car GPS, it will warn you a turn is coming, and tell you when to turn (with text and a beep)Yes, for courses you have downloaded from your computer
Preloaded basemap?Yes, preloaded Garmin Cycle Map with bike-specific navigation so it can give you turn-by-turn navigation instructionsYes, but very basic. It's just to give you a rough idea of where you are
Ability to add maps, such as optional City Navigator® maps or Open Street maps or topographical maps?YesYes
Points of Interest (POIs) specifically for cyclistsRequires optional City Navigator® maps to access general points of interestNo
Plan and download new routes to follow (a route is a sequence of waypoints that leads you to your final destination)Yes. You can upload routes you create elsewhere, and follow them; plus you can also enter in an address on the computer itself and it will create a routeYes. The Edge 520 lets you upload routes you create elsewhere, and follow them, using pretty basic breadcrumb directions

Bottom Line on the Differences between Garmin Edge 820 and 520

Either one of these bike computers is excellent if you jut want to train smart with a premium bike computer. However, if you want great maps and route calculation and navigation then the Edge 820 is certainly the right choice.

Also, a key issue is whether you prefer button control or touch screen control. If you prefer buttons, the Edge 520 is for you. If a touchscreen is a must, you will be happier with the Edge 820.

It’s a tough choice, but someone has to make it. Good luck, and have fun!
