Edge 520 - courses no longer 'working'

Former Member

I have had an Edge 520 for about 18 months and have successfully used courses created on Strava on it - standard procedure, drop the .TCX in to newfiles and it appears on the unit.

Until yesterday!

  • Courses put in to newfiles did not appear.
  • Existing courses would not delete on the 520 - and when I tried to delete individual existing courses the name of the course went blank or to a single character.
  • Factory reset of the 520 did delete the existing courses.
  • New courses would still not load from Strava via NewFiles
  • I can get a course from Garmin Connect, loaded via "send to device", to appear, but trying to load it for a ride the 520 says "invalid course, delete?".
  • Deleting the course uploaded via Garmin Connect doesn't work either.
  • I have tried a few things which may have affected it from a file system stand point (e.g. no spaces in the course name, not starting the file name with a number - I was hunting for a solution, these two feature never caused an issue in the past and didn't fix this one).


Any ideas, any similar experiences? I am rocking firmware 12.10

What absolutely sucks is I am currently on holiday in the Cote D'Azur and am having to use top and use Google maps to navigate instead of my Garmin!!!
