Suddenly Garmin Express can't write to my Edge 520. It started with User Settings (after I changed them in Garmin Connect). When I removed the device from Express and added back, it wanted to write 5 files (power zones, HR zones etc, user settings...) I get an error when it tries to do this. I can sync workout files without a problem.
I can write to a 920xt leading me to believe it is the Edge 520. \
Anyone have any ideas? Could the storage on the Edge be corrupted?
Thanks
