Like my 820. Mapping is good. Display is good, I can have quite a bit of data on there and it’s all easy to read. The touch screen is ok (though water pooling on it does make it go a bit crazy, and it’s a bit hit and miss with thick winter gloves.) It would be nice to have another couple of buttons to use with the ability to turn off the touch screen (I think maybe it can be locked.)
Connected stuff with the phone is good. Automatically uploads rides (can’t remember if the 800 did that, I think the 810 did.) Connectivity from phone is good too with it displaying incoming messages and calls. It’ll also upgrade itself and connected devices via Wi-Fi, which is nice.
Prefer the way it manages devices, it’s just a long list now and it connects to what it can.
Battery life is ok for me.
When I do use the nav stuff I like the garmin remote too. On a road bike I can switch between screens on the drops if I need to check the map. But then I think that works with the 800.
Software seems ok to me. Most regular annoying “feature” is it bouncing the ANT+ stack and everything having to reconnect (and invariably one of my ant+ things don’t.) Most rides it won’t do it at all, but occasionally it’ll do it a few times in a ride.
Re the mapping. I don’t use it that much. Usually on holiday where I’ll quickly knock up a route on garmin connect on an iPad. Then transfer it to the 820 via my phone. Sounds fiddly but isn’t. Even the garmin connect website isn’t that bad these days.
50% increase in battery life interests me. My rule of thumb for the 800 was/is 9 hours on the map screen and 11 hours on the data screen; what are you getting?
Hmm I probably get less than this from the 820. Ride about 12 hrs a week and need to charge at least once a week. But then I do have it permanently connected to my phone during rides for notifications. And I run about 6 different ANT+ devices so it’s doing a lot of comms. Disable the bluetooth notifications and it’ll run a lot longer.
