I have been using my Garmin Edge 820 for about six weeks, including a trip in the Canadian Rockies. I have found the Edge 820 to be very accurate in the data that it provides (speed, distance, heart rate, elapse time, course, altitude), and very reliable. The battery life is better than my Edge 800. I do not usually answer my phone or respond to messages while I am riding, but the blue tooth connection to my smart phone is very convenient in telling me who is messaging or calling me, thus allowing me to answer or respond if I need to.
I may have reviewed this already but I don't see it and now I have been using it for about a month. I agree with people that say the touch screen is not something for Garmin to be proud of. It can take several taps to get it to respond. It, therefore, is not up to date in this technology. That said, it otherwise works extremely well. I am not sure it is worth the upgrade to a so-so touchpad from the button 520 model, but it is very good. The one thing to note is that the beeper (if you are using a Garmin Varia with it) is quite faint. Use the included handlebar mount and I can't hear it at all. However, use it with a 3rd party mount that is metal and open in the back and I can hear the beep every time. Another minor problem is how long it takes for the incline percent to measure correctly. Not that important but it should respond better. Overall, despite that, very happy with it. Also, there are many display options to make it better set up for you.
I absolutely love my new Garmin 820. The pinpoint accuracy, all the available readings, the ease of setting it up and moving from one bike to the other, the Bluetooth and the map is great... just need to get used to a small map.
Transitioned from Garmin Edge 510 to this 820. Hasn't been a smooth transititon. Syncing via BT to iphone is clugey and inconsistnt, syncing with Garmin Connect, much the same. Have twice satarted a ride after pulling 820 off charger, only to have it die 3 minutes into ride. Apparently when synced to BT, it may not power down, or apears to power off then doesnt fully, so continues to run down-even connected to charger! Calling Garmin service support has been a nightmarish experience as well. In the past, customer support has been GREAT, but current hold times are in the hours. They may or may not call you back with experienced support. Thank goodness for google and you tube. Unless the 820 improves, likely my last Garmin device.
Moving up from my Garmin 500 to the Garmin 820 is night and day, I only have more pros than cons since I only had it only 2 months in use, but its definitely technology in the right direction.
If you're as tied into Garmin for your training needs like I am, then this is a great addition. The data and its integration with Garmin Connect and other sites is great. The only downside is the touchscreen is not that great. The 800 was better but the 800 doesn't integrate with Varia Vision
I had a 510 that worked fine but I wanted to upgrade. The upgrades were the color touch screen, improved maps, and a few minor software things. The display is good, but essentially the same size as what I had. IMHO the 1000 is too big and the 510 is too small. The 800 seemed to be Goldilocks, but for some reason Garmin didn't stick with it.
I purchased the 820 to replace my 800 with map card. It is a little smaller and I like the new features like how it links to my iPhone. It came with an out front mount which was a nice touch. I like lots of data as I helps me focus on something other than how tired I am.
I previously owned a Garmin Edge 1000. I use the computer for training rides and racing - occasionally venturing out on long exploring rides. The map on the 820, although smaller, works just as well as the 1000 ever did. Sharp resolution. And the control buttons on the 820 are much more crisp and positive. I also prefer the smaller size.
Traded up, finally, after years with the 500. Works well but with two minor quibbles. First, the screen is more difficult to see in bright light. And secondly, when wiping sweat droplets off the screen, I sometimes inadvertently change pages, which can then be difficult to swipe, especially on the fly. That alone makes me almost prefer buttons instead. A little pricey compared to competitors, but okay if you catch a sale.
I really like this unit so far. It has a nice, compact size that blends nicely with the front of my bike, it picks up gps signals almost instantly and has been very reliable so far.
The mapping works well but don't buy this unit if you're big on mapping because it is simply too small. Go for the Edge 1000 instead.
I also have an old Edge 500 (bombproof!) and an Edge 1000. The new 820 has a longer battery life than the 1000. The navigation is of course not quite as visible, given the 820's smaller screen size, however, it still navigates well...even on dirt trails. They have improved the software, with the latest update allowing 3 different 'sensitivity' settings for the touch screen.
I love the Edge 820. This has to be the best bike gps on the market. It's calculates everything, gives u a map of ur rides, and when ur friends get 1 u can challenge and have fun with them. I never thought my friends would get one because there so expensive but one did and now we try and beat each other's times when we're not riding together. So, If ur thinkin abt getting one, get it. U won't regret it.
Returned the Edge 520 go the Edge 820, both worked fine, however I wanted the touchscreen. This was an upgrade from the Edge 500.
Saving your data when paired to your cell phone is fast, getting you kudos from friends on Strava.
Im still figuring out all of the features it did cause an alert to my emergency contact when I stopped for an adjustment.
Love my Garmin.
I use(d) the 820 Edge (and previously a 520) to plan routes on my computer using Ridewithgps and then transferring them to my garmin device. Also to log my rides by transferring data back to my computer. Unfortunately, the Garmin devices have a persistent problem communicating with PCs, which is well documented in online forums. After a while, the PC will not recognize the Garmin when it is plugged in. I returned my 520 twice ($99 each time) for replacement refurbished ones. The 820 is approximately 6 months old and I have already returned it once for a replacement. The support page has a procedure for fixing the problem, but it does not work consistently. I really like the thing when it works, but it is useless to me when it doesn't.
Great product features. Good size, combines touchscreen functionality of garmin 1000 with the size of the 520. Rides upload immediately to StravaGarmin Connect via your phone or WiFi, you can see incoming texts and calls. Touchscreen though was abit of a setback. Abit difficult to use especially when riding. Does not perform like the smartphone screens to which so many of us have become accustomed. But overall, Im very pleased with the product, still a recommended buy.
