Yes, it's old, but it does what I want, and I like it, so I'm making one final effort to get it working again.
The trouble started last week when I plugged it into a windows 10 PC to upload rides. I realized that it hadn't been recording for a few weeks.
Seemed like it might be full. Checked the properties in Windows Explorer and seemed pretty full. "Activities" wouldn't open in the Windows Explorer.
Did a factory reset.
Still can't open activities. When I check the ride history on the device, it says there are none. But when I check the properties in the Windows Explorer, it says there's only ~360KB of unused space. And yet all of the items that show up in the explorer claim to be tiny files and folders.
I think it's got a huge amount data on it that's not showing up in the Explorer.
When I try to use it on the bike, it says it connects to satellites. When I ride, it shows speed but not distance, and it doesn't record any ride data.
I'd like to wipe it and reinstall all of its software, but I can't find a way to do this. When I connect to Garmin Express, it says I'm "up to date" and says it syncs. But it doesn't give me a way to wipe and/or reinstall Garmin software on it. The options under Tools and Content don't help.
I could re-format it from Windows, but I don't know where/how I'd be able to put the original software on it.
Any advice?
