I used to ride with a regular GPS on my handlebars to map the trails in my area. It was big and would rattle which was annoying. The place I ride most has 69.8 miles of trail. That GPS was the only way I could find my way around sometimes. I bought the 820 so I could put all my tracks on that and navigate easier because the screen would always be on and it doesn’t rattle. Imagine my surprise and amazement when I discovered most of the areas trails were already on the 820’s basemap! And this isn’t some insanely popular riding area either. This is Manchester Connecticut and surrounding towns. Not exactly known for mountain biking like other places. The ability to download people’s rides on Trailforks is a game changer.

Great Product but could be better.

The auto dimming feature was particularly useful at night as well.Crash detection worked (tested it by throwing it onto my bed).Battery life is more than a handful as my rides rarely go above 4 hours.I also liked the fact that Garmin connect allows users to download *apps* onto their Garmin.One thing to note is that if you're not staying in the UK or the EU, you'll have to purchase a region specific map from Garmin's site.That can be tricky because navigating to the right map for your Garmin in your region proved to be quite a challenge. Their website like their products have pretty poor UI.All in all, I would say it is a great cycling computer. The little quirks I've had with it can be overlooked as it does it's function really well.I would have rated it excellent if not for these little issues. The price is pretty astronomical as well!

Garmin Edge 820, a great device and a nice upgrade from my previous Edge 810, does everything that did and better. Though it has a slightly smaller screen size it is sharper and easier to read and great in direct sunlight with the backlight off. It finds satellites instantly (even in doors) so you can set off straight away instead of waiting around for it to get a signal before you can leave.I do recommend this device but it does currently have a few software issues which I'm sure Garmin will sort soon in an update such as pausing a ride and turning the device off to resume later which will cause the device to freeze when turning back on requiring a master reset and also the screen touch sensitivity can be a little bit too much at times, I can hover my finger ... MoreGarmin Edge 820, a great device and a nice upgrade from my previous Edge 810, does everything that did and better.

The Wifi is very useful for uploading your rides once you've finished, you can also do this with connecting your phone via bluetooth but sometimes my phone is almost or totally dead by the time I'm home.Overall a great device, recommended upgrade from previous units.

Great device - Ok Touchscreen
12 April 2017

Nice and small but packed with features. This device does almost everything I could imagine. The group tracking feature is awesome on long rides with your buddies (Who also have a compatible device). I would say this is one of the best features of the device. The bicycle specific navigation is pretty good but I rarely use it. To be honest - in most cases its easier and faster to grab my phone from my jersey and get directions from it. I wish Garmin allowed you to create a course or directions from your phone and then upload it to the 820. I believe there is a 3rd party app that allows you to do that.Last but not least - the touch screen. Garmin should have left the side buttons like on the 520.

The touch screen is useful when using navigation and other stuff but is a royal pain to use while cycling. Give me real buttons! Garmin does make a remote for it but thats another gadget that I have to remove when I go in the store or commute to work. Also if you get dirt or water on the screen it can sometimes make the screen go crazy. There is a sensitivity setting that you can adjust if that happens. I put a glass screen protector on mine and haven't had any issues the touch screen going crazy and have ridden 1000+ miles in the rain with the 820.Is it perfect? No but its a really good bike computer. Give it a shot.

As a long term Garmin user I needed a replacement for my Edge Touring. This model does much more than the touring and benefits from WiFi and Bluetooth connectivity. With this I can seamlessly download pre planned routes from Strava or Ride With GPS. And when I return, the Edge 820 has uploaded my ride to these websites before I am in the door. Halfords we’re trying to bundle this with Garmin handlebar mounts. Don’t be taken in by this as your purchase will come complete with a standard mount, together with an out front mount. I have reduced my star rating to four as the touch screen doesn’t respond well to swiping when hands are gloved. However, you can set the unit to automatically scroll through selected pages, so this isn’t a major issue.

Inaccurate and unreliable. Returned it.
31 May 2017

I started out with an Edge 500 years ago and had no real complaints, mostly because it was my first real experience with a cycling GPS. In hindsight, it takes forever to acquire a signal and the signal would occasionally cut out in the mountains, but it was still a good unit.I fell for the instant upload to Strava thing and bought a 510 when they came out and again, no real complaints, other than there really wasn't any real "wow' factor over the 500 aside than the wireless upload. The display was tough to read (I actually preferred the display on the 500). I regret spending the money on the 510, I should have just stayed with the 500.Didn't go for the 520, but bumped up to the 820 when it came out. It was vastly better than the 510 in my opinion.

The processor was faster, the touch screen was better, as was the display. It was what I had hoped the 510 was going to be when I bought that.Then the bad started with the 820: elevation gain constantly needed to be corrected once the rides were uploaded to Strava. Then I started having it go to the "save ride/resume ride" screen mid-ride, and with ever-increasing frequency. That was it for me. I did not want to get outside my warranty/return period and have the regrets I did with the 510. I returned it and went with an Edge 25 on sale and haven't looked back. I still have my 500 and my 510 if I need them, but I doubt I will. I'm all about the minimalist approach now.

Significant Upgrade from the Edge 800
26 May 2017

1st off let me say that I got this for $390 (US). Which is over $100 discount for anywhere else, so thanks Evans Cycles for that.I've been using a Garmin Edge 800 for the last 10 years. So all of my comparisons are going to be in relation to the 800. That being said the Edge 820 is fantastic. I rely alot on the mapping feature. I upload maps i created from Garmin Express and I'm off and running. A nice touch to the 820 is that you get a beep from the unit when you are 1/10 a mile away from an upcoming turn and 2 beeps when your 200 yards away...really fantastic! I can keep my eyes upon the road now.Out of the box it comes loaded with the European maps which I easily added a US set of maps to (goodbye micro SD cards). I did a couple of rides with the 3.30 ... More1st off let me say that I got this for $390 (US).

I can keep my eyes upon the road now.Out of the box it comes loaded with the European maps which I easily added a US set of maps to (goodbye micro SD cards). I did a couple of rides with the 3.30 software version and saw some of the discrepancies others have complained about. The altimeter was way out of whack. I then upgraded to the current software version (7.0) which corrected a few issues. The 820 gives elevation gains in 20 foot clusters (approx). And while the altimeter had an almost 12 second lag to the gradient, the newer software has it down to 3-4 seconds lag on gradient. The Edge 800 gave both gradient and vertical in MUCH better real-time. Hopefully the future software upgrades narrow that gap. The new speed/cadence sensor is a magnificent improvement over the old GSC 10 which was zip tied to a chainstay.When you finish a ride the 820 gives you a nice ride summary and based on your personal effort a recommend recovery time before you should ride again....really nice.The Edge 820 has a sleeker profile than the 800, 810, and 1000 and you won't even miss the bigger screen. Big thumbs up for the Edge 820. Hopefully Garmin makes some improvements to the real time aspect on the Gradient/Altimeter. But at the end of the day the vertical ascent numbers are spot on. The only downside I've noticed to date is the lag time on the gradient.So I highly recommend this unit (after software upgrade). And I haven't even used the Strava Live or power meter functions yet.

Underwhelmed
17 March 2017

I'm invested in the Garmin eco system having had various devices over the years. I would recommend this device but I think my expectations were a little high.I longed for mapping and turn by turn functionality so I finally treated myself to one. I opted for the 820 as this one is deemed the smarter offspring of the 520 and edge 1000 according to DC Rainmaker.Already having the forerunner 320xt I already had most of the functionality that makes the edge special minus the mapping and directions.The touch screen is not a sensitive as i would have liked. Even with the sensitivity turned up to high you have to make very definite gestures to get it to respond. On the plus side this doesn't appear to be any worse when wearing gloves.I would have preferred a button ... MoreI'm invested in the Garmin eco system having had various devices over the years.

Even with the sensitivity turned up to high you have to make very definite gestures to get it to respond. On the plus side this doesn't appear to be any worse when wearing gloves.I would have preferred a button to toggle through the various screens during my ride but unfortunately you need to tap the screen to activate the menu then use the arrows left and right. I feel this could cause an accident. I'd recommend setting a custom screen for your ride and don't mess around while riding.The turn by turn directions are a little off, Sometimes prompting once I'd already made the turning. When taking a wrong turn it can take up to a minute to recalculate. The route planner also insisted on leading me off the main road constantly on what was a simple A-B commute. Mapping on strava and exporting the GPX file is a little better.The address finder is also a little quirky, taking the first part of a post code followed by a sluggish response to selected the number from the second part of the post code. Then the house number then the street name which try's to autocomplete after a few characters.This is not a cheap item by any means I opted for the unit only as I already had HRM and speed/cadence sensors, I was initially underwhelmed with the product and considered returning it. I would say give it time and get used to the little quirks. If your new to garmin and smart devices you'll be impressed.Currently there isn't a better device out their to my knowledge so I'm learning to love it.

Worse than the edge 800 which is 6 years older
1 August 2018

This could be a great product but it's plagued by usability issues. I would give it 3 stars except for one fact -- The edge 800, a unit that is 6 years older, is better in nearly every way. That's just unacceptable.Negatives, compared to the edge 800:- The touchscreen is horrible. It's utterly impossible to use without devoting your attention to it and you often have to do the same thing 2, 3, 10 times before it registers.- The unit is slower than the edge 800. I loaded the same openstreetmap files onto both units and the edge 800 both draws maps and routes noticeably faster. I don't even know what to say here... They obviously didn't want to spend more than 7¢ on a processor if a 6 year old unit beats it- The thermometer takes forever to catch up.

They obviously didn't want to spend more than 7¢ on a processor if a 6 year old unit beats it- The thermometer takes forever to catch up. After a 30 minute ride at which I knew it was 37º C out it was still only at 33º, and raising 0.1º every 30 seconds or so. The edge 800 takes ~5 minutes- There is no "home" button, so from settings you often have to tap back 4, 5, 6, 7, 8 times... And when your taps only work half of the time...- GPS makes insane jumps more often than the edge 800. No, I didn't just go 2km away and back in 0.1 secPositives, compared to the edge 800:- The GPS sync is faster- It looks nicerI don't have anything to say about the advanced features of this device, like wifi sync, etc as I didn't bother to use them. This device is an utter failure at its core functionality so the advanced stuff is meaningless.

Worthwhile upgrade
15 January 2017

I have used a garmin 305 for the past 10 years and its served me very well. However I had a 'big' birthday coming up and wanted something that does true mapping as well as being able to make use of cadence and separate speed sensor. I had a long hard think about buying the 820 or the 520, the non touch screen 520 would have been great if only it had mapping, so in the end I plumped for the 820.My initial impression of the 820 is that its very small and neat. It picks up the satellite signal quickly and really has so many features that it will probably take a couple of months to work out exactly what i want display on screen during the ride. Do note that some to the more advanced features expect you to have power pedals etc if you want to use the advanced cycling ... MoreI have used a garmin 305 for the past 10 years and its served me very well.

Do note that some to the more advanced features expect you to have power pedals etc if you want to use the advanced cycling dynamics. I don't have these but still think I have more than enough information to keep me busy post ride.The unit and sensors were extremely easy to fit with all the sensors already paired with the device.Data transfer is so easy with wi-fi and if you pair the 820 to your phone via bluetooth you again have access to group tracking as well as live tracking etc something i plan to try in the near future so my loved ones can see when I'm getting near home.I bought the 820 in between Christmas and the New Year so had a bit of a wait to receive the unit after the Christmas holidays and an email from Vanilla bikes just to keep me updated on progress would have been nice (this may be just my impatience to get my hands on my expensive new toy!). However the 820 arrived fairly quickly after the hols and for the price I paid in the Christmas sale I'm very happy.So...I'm happy with the 820, very happy with Vanilla bikes, their prices and service and will now consign the 305 to mountain biking until the 820 has a few years on the clock
