Map of walk previous done
I dont know the FR55 at all, but from what I see FR55 has no breadcrumb navigation
Have you sync'd with Garmin connect? Maybe the route shows there on the activity?
It's shown me a map of a walk I've done previous but stopped on the 20th January.
Are you sure the GPS is enabled? Sounds like it got disabled.
Download either "Hiker App" or "Hiker DF" and try with that. You'll see a GPS indicator icon to the left of the battery in the bottom with 4 different colors (green on the top) during the whole walk.
