I dont have an 820, but have the 1000
the guy who done the review keeps on complaining about the screen sensitivity when he swipes the screen. He obviously is unaware of the Garmin remote gadget .... press a button and you flick between screens. Garmin should include this in the package of the unit:
https://buy.garmin.com/en-GB/GB/p/146078I have one but never use it as my screen and unit is set up properly (for me) .... I have the front page setup showing my speed, average speed, cadence, average cadence, distance to next turn, total distance, and heartbeat (I don't have a power meter (yet))
this is the screen that is on the first screen and stays on during the whole duration of my ride until I need to make a turn ... When I need to take a side road/turn, I get a loud beep and the screen swithes to the map screen showing me where I need to turn. Once I've turned, the screen switches back to my main screen showing speed etc
but my question is .... why the heck do you want to flip screens during a ride if you have set your unit up correctly with the data thats importsat to you?
I also have the Garmin Varia Radar connected, so when a car approaches from the rear, when it is approx 200 meters away, I get a loud beep and a dot appears on the bottom .... as the car approaches, the dot moves up the screen .... when the car is beside me, the dot is on top of the screen .... this unit is a 'must have' IMHO as it makes cycling a lot more 'stress free'
The Garmin units are pretty complex, and you need to know how to set them up .... I doubt that the guy who done the review done his homework on how to set the unit up
You need to read this forum on a regular basis (if you own the 820):

https://www.dcrainmaker.com/2016/07/garmin-edge-820.htmlwhen I bought my Edge 1000, I knew beforehand that it had small glitches, such as switching off during a ride, but I also knew/know that it would be 'eventually' sorted
I had a few glitches on some of my rides, where the unit switched off during a ride, but when I switched it back on, my data was still there.I lost a minute of ride time and I got home with no problems
since loading the new software, the unit has not switched off and everyting works like a dream .... no stress on a ride on a road that I have never been on, all data works fine
my unit is the Garmin Edge 1000, and if I had to choose again, I'd get the same .... I think that the 820 is similar, but you need to learn how to set it up....
I learned lots from this site (read the comments aswell):
http://www.forgot.co.uk/garmin-edge-navigation/garmin-edge-1000/can any of the other units on the market offer the same features?
bottom line.... it's a kak review from someone who never done his homework, and who does not have a clue
