I have a Garmin Edge 810 paired with my Android mobile on which I run the Android Garmin Connect.app.
Most data, eg Activities, Courses synchs happily between the Edge 810 and Connect.
However the Locations data - personal POIs if you like - can only be created and viewed on the Edge 810.
So I have to back up that data manually by copying the Locations.fit file from the Edge 810's memory to my PC. And I don't get to use the Locations when creating a course via the Android Connect App.
Any reason why the Locations are omitted from the many types of data which synch?
