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.
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.
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 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.
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.
I use the Edge 820 on both my Mountain and Road bikes. It replaces an Edge 800 used on my Road bike and an Edge 500 used on my Mountain bike. The screen visibility in both low light and bright light is superior to my other Edge computers. Set-up was easy. I like the way ride data downloads wirelessly to my cell phone ap. Overall, very happy with the purchase. This is my third Garmin bike computer and the best to date. The purchase from WBW was easy and a good value.
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.
I've had the 820 for about a year now and here are my thoughts.
Things it does well
Connect to a bunch of sensors flawlessly and easily, connect to phone via BT much better than my Garmin 510, group connect works well, navigation works well and workout screens are ok. Connect IQ apps for training peaks is very nice to have.
What I don't like
The touchscreen sensitivity annoys the hell out of me and if the 520 had group connect I would never have bought the 820.
I'm not a techie, so the fact that I could set up on my own without instructions says a lot. I love the voice navigation via iPhone, map has section with turn-by-turn directions, courses work well and the ability to put in a destination and the app guides you there is pretty great. A must-have for anyone who wants a very usable bike toycomputer )
This is my 4th Garmin device going back to the 705 and all of them arewere very good. This newest one (for me) tops them all with all its features and connect options including being able to connect to your phone and to other Garmin devices. Maps are also very intuitive and has never given me any issues.
I map routes on Ride with GPS and upload them to the 820 which automatically syncs with Garmin Connect and my phone. Good battery life. Simple to use. Improved accuracy over the edge 800 I used for several years.
