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 use the Edge 820 mostly for pure navigation, with little concern for training metrics.
After a rough start, I learned from fellow 820 users that when using a course developed in RideWithGPS, best to download as a TCX file, and never accept the Navigate To Start? prompt. Following these two tips, I have enjoyed a series of flawless navigation performances, including course types that used to trip up my Edge Touring, like heavy greenway content, out-n-backs and lollypop loops.
Well, the navigation has a mind of it's own. You know how to get from A to B but I guarantee that this navigation will take you to C and D first. One you realize you have to be smarter than the device you learn to accept its flaws....it's a tiny brain. My only recent gripe is that it's supposed to keep a list of your addresses you go to as Recent Finds. Since the 11.2 upgrade, my device no longer does that. Garmin support has not been too helpful so far. Another little annoyance is that it often will not remember to connect with cadence sensor and I have to do so manually. Like I said, tiny brain.
Horrible battery life compared to other models, even with most features disabled.
Touchscreen can be problematic to operate, esp. when there is precipitation.
The amount of features are amazing but after a while you start to ask yourself just how many you actually need. I found myself disabling most either out of the need for simplicity andor improving the battery.
Latest firmware upgrades corrupted the sync process (11.0 fixed finally).
In doing some research, the 500 series seems to be a better fit for me and will deliver much better battery life, i.e. it will survive 75-100 miles for a ride with juice to spare.
Sorry, Garmin, this unit was a bit underwhelming for what I paid.
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.
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
While smaller than the 1000 it has all the features you need and easy to operate. The buttons are easy to access, touch screen works well and easy to read.
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.
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.
I was apprehensive about getting this due to Garmin's track record of having software bugs that take multiple version upgrades over a year or so to work out, however this one so far seems to be right on arrival. Mine came with version 2.4 which worked fine the first few rides. A new version was available (3.1) and I allowed the upgrade and it still works great. Zero issues. The mapping is nice and the touch screen while perhaps a little more sensitive than the 510 is not an issue for me, and it's actually bigger than the 510 while the body is smaller. Being smaller is possible due to the location of the buttons for startstop and lap being on the bottom edge, not the screen plane bottom like the 510. The location of the buttons with a KEdge mount does make it a little tighter getting to them because there isn't much room between the bar and button to stick your finger in, but you just need to bump the switch lightly so it's not an issue for me. I like the auto dimming screen too. Auto upload is nice. It will be interesting to see what IQ apps are available in the future for this. There are some interesting ones with quite advanced training metrics to use during a ride. Some are free and some you will need to pay for. Right now, very happy camper. I'll update if I have any issues as I get more use with it - right now I've had it a week and have about 200 miles over 6 rides on it so admittedly limited data.
A great garmin at a good price. Replaced my 810 with this 820 and the only new feature that I use is the ability to sync over WiFi. Overall a great unit at a decent price.
I use it for countryside riding and really like the pacer mode, maps, and the plethora of usual (time,speed,distance...) stuff. I like the terrain mode but dont know where I am in the screen.
I upgraded from the Edge 500, which I've been using for years - mostly I was looking for map capability for taking off into the country to chart new territory.
This is a worthwhile investment - tons of available information, easy to program and easy to use.
The only complaint, minor as it may be, is battery life seems to be about 12 of the Edge 500. I understand the additional capabilities eat more juice, but I'm used to recharging every 12-15 ride hours...now battery is low after 6 hours of saddle time.
Other than that, it's got a great display and lots of features and options. I considered the Wahoo Elemnt Bolt, but I don't regret the decision to stick with Garmin.
Once set up properly, which took a bit of studying, the unit works fine. I like how easily the head unit is Integrated with the sensors. The software is so so in the user interface department, which is SLOW, for 2019, standard. This is really annoying, and distracting, when you are riding.
My biggest complaint has to do with the screen. It is basically as good as my Palm Pilot from about 2004! The color and resolution on the screen are not acceptable in todays standards. Garmin, for charging $400, you can do better than that.
The few times I was caught in the rain when I was riding the screen when crazy! The rain drops randomly changing my screens and settings. I guess I could have changed the touch sensitivity then but I was too busy to not cause a crash in the pace line.
My 820 is out of warranty now so I will be replacing it with one of their competitors when it dies.
