USG_TECH10 - I'm not sure I understand your request. On what page of the manual should I look?
Alos, the issue is because I have 10 activity files. They represent a 1200 km ride broken into 10 pieces. I'm riding the entire 1200k route, but I would (ultimately) like to name the activities Leg1, Leg2, Leg3, etc. But, what I have is 10 files with date/time stamps. They were uploaded to my 580 in order of their Leg and the times indicate that. But, when I look at those 10 activity files in my 580, they are not in "Time" order. They are in a random order. This means that I need to somehow correlate that silly time/date name to a specific leg of the route on which I'm riding. Does that make sense?
