Hi, I've updated a .fit file (also tried a .gpx file) to my Forerunner 945. It shows as a saved course, but when I select it "Do Course" it freezes on the "Loading" screen. I've tried turning it on and off. As mentioned, I started out with a .gpx file which did the same thing then converted the file to a .fit files and same have the same issues. The .fit file shows to be 118,643 bytes in size. Anyone run into this issue? or can help? Thanks!
