Hit mark to save my starting point. Do my hike, a few hours later return to my starting point. I save my route in track manager. Or at least that’s where it ends up. When I go back to check all the data, everything looks right except the mileage. In all 3 hikes I saved it shows some random off the wall distance. 157 mi , 194 mi last one is 9313 mi. I realize I’m probably not doing something right but can’t figure out what. This is a pretty easy GPS to navigate with. Any help would be greatly appreciated.
