Hmm, so over the last couple of weeks, I've killed my old Edge 800 (again) by drowning.
Previously, I've repaired it with new daughter-boards, but I can't get them any more.
I might fix it again with board-level repairs with replacement USB connectors, but now is not the time.
I have a big event coming up, and need to be confident in the device; so I got a new 830 a couple of weeks back.
Things I like:
-The screen is *much* better. Higher res, and better visible in sunlight; text is much better resolved.
-Hot-shoe power charging. USB charging in the wet was the main cause of death of the old 800.
On the upcoming 1200, I will have the device fully-charged, and 2 Garmin power banks. I will run off one, till it is low. Then swap it for the other, whilst re-charging the first from a HBFO battery pack. Yes, not the best, charging-a-battery-from-a-battery-from-a-battery. But the bike I'm using doesn't have a dyno-hub. The same set-up will be used later in the year on another longer ride, on a bike where there is a dynohub, and the plan is to charge / swap alternately.
Things I don't like:
I've disabled the WiFi connection. (It's brainez are too feeble to connect to the type of WiFi I have here.) But it keeps turning it back on again!
I've always used Garmin City Nav maps before (perhaps not always legit copies...), but the new unit came with Garmin's OSM-derived cycle maps. They are very good. Garmin have put in some effort to make then useful on a bike unit. I will use their South America maps later in the year, they seem OK too.
