Has all the features of the Edge 1000 (plus a few more) in a compact size.

Its a good size, it was easy to configure and operated flaulessly during my time on the bike this weekend

This is like having a laptop, iPad, and GPS all packed into a perfectly sized package that sits over my bar stem.

(I don't ride 15-hour days, but for anything else it is fine)- it picks up satellites much more quickly than my old Edge 500, generally in under 15 seconds- the screen is a good size and clear, and very

The 820 is almost perfect--perfect size, the navigation is great and the screen is clear and easy to see in the bright sunlight.

I paid full price for a new 520 and it worked fine for a while, then suddenly my computer would not recognize it.

Got a great price in Amazon USA to be shipped to Australia

There are other units out there with competitive prices; nobody should have to deal with this nonsense.

As a conclusion, I could say Edge 820 is excellent, but I'm not sure if it's worthy upgrading from 810.

Overall, I count this as a very good upgrade, although some features could be a lot easier to work with.

As a previous owner of Edge 810, I found Garmin Edge 820 a good upgrade in screen resolution, internal memory capacity (although lost capacity for external memory card) and some software improvements

So I loved it during those few months where it worked as it should most of the time.

I’m not sure why the reviews are bad but the 820 has been great huge upgrade from 500.

It seriously, really does detect traffic approaching from the rear and does a really good job of showing you where it is and how fast it is approaching

Having purchased several Garmin products over the years, I know to avoid them for the first year since I have learned that Garmin does not do a very good job testing their products before they are released

But it still lags a bit, which was never an issue with the 510, and I generally think they could have done a better job with the UI.

The phone would see the device, pair up... and just would NOT connect, even with the app downloaded from Garmin (whose web page links were all broken, btw... nice job, Garmin).

The problem is its flawed, and for the price Garmin should have done a better job

There are other bugs with the 820 series as well, including but limited to - bluetooth issues with Iphone connectivity to garmin connect app, text messages not consistently appearing on the screen, device crashing mid ride after 100 miles (data lost), device locking if you try use zoom function on map screen, unreliable "IQ" feature

It has great features, but it is so buggy and underpowered in so many respects that it's constantly frustrating to use it

Then, it started to recalculate the route even though I had that feature disabled.

The 820 is a nice unit and a nice package with some great features, but it is not stable

it might be a great feature for the trainer, but not out on the road.

So, if you care about intuitive and reliable navigation, I can actually, for the first time, recommend a Garmin unit

So I began trying to load the route while still indoors, without GPS reception, but that seemed to create unexpected navigation problems and more freezing (see #2 below)

I'll separately post a review there when I've run it through some more paces, but, significant positives include: (i) super-long battery life (I’m getting close to 15 hours); (ii) no touch screen – you use buttons to cycle pages, and also buttons to zoom in and out (both on the map and on data screens); (iii) super-good clarity in sunshine; (iv) the turn-by-turn navigation just works

It crashes often, turn by turn navigation fails (works in the beginning, but then stops to work during a tcx course)

So I loved it during those few months where it worked as it should most of the time.

GPS easier to use than cell phone which can have gaps in coverage.

I would much rather stay with a non-touch screen model and an older model with a much reliable GPS system

I think it's quite likely that my unit has a bad GPS

iPhone BT connectivity issues (GPS location on the iPhone jumps 1,000s of miles, while GPS on the 820 appears correct)I am a MTBer and bought this device to get accurate mileage, cadence, and ascent/descent data, and was compelled by some of the other features like incident detection, text and caller notifications.

What good is a GPS that loses turn-by-turn directions when you're 200km into a ride and you happen to get a little tired or you take a detour

Great mounting options and pretty easy to set up initially

cadence sensors work everytime, good mounts for road or mtb

I anticipate for the future are those flimsy little mounting tabs on the backThey have broken off on every

Great mounting options and pretty easy to set up initially

The mount that goes to the front is excellent.- Installing the sensors and pairing them is easy

I owned the Garmin Edge 800 previous to this and was frequently having problems using the routing

For whatever reason the unit then becomes confused during the ride and tells me to take a random turn not in the route until after about 100 feet it tells me to complete a U-turn and gets back to the correct route

I’m toying with returning the Wahoo Bolt (EDIT: I did) and buying the more expensive Edge Explore 1000 (gulp), in the hope that it combines the best of my old 800 (usable touchscreen, good routing, good CPU for fast redraws and a usable map page) with the Bluetooth/integration features of the 820 (Varia radar, incident detection, etc.)

if you look on the map on the 820 while this is happening it graphically shows the correct route on the map

I love the functionality of Garmin cycling devices, particularly planning routes on my PC and transferring them to the device.

I bought mine in August and the unit have been plagued with issues

In trying to squeeze decent (not great) battery life out of a compact unit with tons of features, I think Garmin massively under-powered the CPU on the 820

The 820 is a nice unit and a nice package with some great features, but it is not stable

Again, I suspect this has to do with the CPU and the many functions the unit is trying to support

As mentioned above, the unit inexplicably and unpredictably freezes without warning

It works for recording rides & connecting to Strava but farce less expensive bike computers do that

Overall, it's the best bike computer on the market for training and racing (until the hammerhead karoo is released later on)

I started tracking my rides with a cheap bike computer

very nice computer, used for a couple months now, very satisfied so far!

The Varia Radar taillight is the best reason to own this expensive computer

Add buttons and lose the buggy touchscreen, and improve the GPS software

I deeply regret my purchase of the 820.Here's the problem: the touchscreen is overly sensitive and a drop of sweat is registered as an input -- I've found when riding it will suddenly go into the settings menu, change screen settings, stop navigation or cancel recording a ride just because I sweated on the screen while riding!Worse, the 820 is utterly UNUSABLE in the rain because it registers every rain drop that hits it as an input

I bought this device on 10/10/16 and was considering returning it, as it was quite buggy, most notably with the extremely sensitive(to the point of unusable) touchscreen.

Add buttons and lose the buggy touchscreen, and improve the GPS software

The previous Edge 810 had a very usable touchscreen, but the 820 either won't respond or there is a 1-2 second delay.

This is something Garmin needs to fix!If you want to try these free OSM maps on your Garmin, DC Rainmaker has a good step by step procedure on how to do it on his website

The folks at Garmin are really giving themselves black eye with these "Free" maps that don't work for the average user.

It seems to me that over time, these free maps have become more error prone, I don't remember the same level of problems from my early days using the Edge 1000 which also shipped with "Free" maps

The only complain is that I didn't like the basic maps the came

so if you are using it with the out-in-front-garmin-mount squeezing your finger between the handlebar and the unit where the lap button is located is difficult (specially when doing laps for intervals), the map is so slow to use, getting to the screen that

Over 18 months of use, with multiple software updates, and still a lousy product

Having owned nearly all the Garmin Bike and Triathlon range of computers, the Garmin Edge 820 is without doubt the worst product ever produced by Garmin

Without question the worst Garmin product I've ever owned--I hate the thing.

I solved that problem with the remote which IMO is the best cycling product I've purchased from Garmin but over all the 820 is a big let down

This is more a reault.of limited offerings in the space rather than the 520 being a great product on its own though

, I have so many times when the screen is just not responsive

But it is going back:- screen won't work with gloves on

The ability to upload a ride via phone or on home WifiIncident detection: Great ideaBetter screen resolution: Looks much better than my 800 model.

A great little device, clear screen, easy to use with all the features of my 1000, only smaller.

(I used a Gorilla battery with my iPhone 6s+ on a 500 mile ride 2 weeks ago, the phone lasted all week on the battery without external charging and the screen is much larger and the maps work great

It crashes often, turn by turn navigation fails (works in the beginning, but then stops to work during a tcx course)

For some tcx files, it gives nice turn navigation and for others it just shows a map overlay and pretends it's not navigating me.

The wise rider will of course continue checking over the shoulder and listening,The downside to Varia Radar is that it overrides Turn-by-turn tour directions

What good is a GPS that loses turn-by-turn directions when you're 200km into a ride and you happen to get a little tired or you take a detour

Some of this is your personal use context: I want excellent and easy (and intuitive) turn-by-turn navigation for my many multi-day bike tours

As a cycle computer, it gives you every you need but the connectivity issues mar that experience

I see lots of folks with Garmin's who like them and have had good experience with them, but in the last 18 months I have had to send back an 800, 810, and now the 820 within a few months of purchase, because they quit working

Initially, I had good experience from the unit

My experience with this product has been pure frustration

In 2017, more than 10 years of high quality touch screens in so many devices I found this very frustrating

I lost 3 years of data when my past app crashed and lost my data.

So I loved it during those few months where it worked as it should most of the time.

And not work a year or two later after a half dozen firmware updates or whatever

and it's my first high end bike computer, so can't give a better review

Even after reading lots of bad reviews of Wahoo element bolt fans

I’m not sure why the reviews are bad but the 820 has been great huge upgrade from 500.

Personally, I don't understand all the bad reviews; however, I have only owned it for 1.5 months.

Despite all the less than glowing reviews, I bought a Garmin Edge 820 anyway

There is a terrible flaw that makes these devices frustratingly useless.

The problem is its flawed, and for the price Garmin should have done a better job

This thing has a rather glaring design flaw in the placement of the start and lap buttons.

So many flaws: hard to see in the daylight no matter how you configure brightness

So I loved it during those few months where it worked as it should most of the time.

No option to "resume later" in relation to #5#10: accumulation height difference over a ride is not correctly calculated (most probably due to bug #3)#11: slow reaction in displaying new course direction after a turn#12: WIFI connection problems#13: gradient lag, slow respond to gradient differences#14:Adding 5000+ miles to a ~75 mile ride (not confirmed by anyone else yet)#15

As a cycle computer, it gives you every you need but the connectivity issues mar that experience

cause every complaint online is basic connectivity issues, which as usual are very basic connectivity problems that people can't figure out which are in Garmin’s app's written very clear to be able to follow

Initially there were some connectivity issues with my phone but after working on it and experimenting with it a little that was resolved

The Edge 820 is DANGEROUS to use while cycling...which means it shouldn't be used while cycling...therefore, it is not a cycling computer.

I’m toying with returning the Wahoo Bolt (EDIT: I did) and buying the more expensive Edge Explore 1000 (gulp), in the hope that it combines the best of my old 800 (usable touchscreen, good routing, good CPU for fast redraws and a usable map page) with the Bluetooth/integration features of the 820 (Varia radar, incident detection, etc.)

Add buttons and lose the buggy touchscreen, and improve the GPS software

: the touchscreen sensitivity is TERRIBLE, it freezes, it takes a long time to switch between screens, it doesn't work if your hands are sweaty (which makes no sense for a cycling computer), the lap button lags, the buttons are now on the side of the unit instead of on the

All the data fields stopped updating, the screen froze, and all it would do is beep helplessly at each button press which failed to do anything
