I am trying to update the maps on my watch to the latest version while the watch is charging. However it gets to about 18% before giving a Map Sync failure.
It is being done over WiFi using Map Manager as I don't have a PC to plug into to do via Garmin Express.
I am running the latest firmware, anyone have any suggestions? I tried setting the display to always on so that the watch was "always awake" but no luck
