My 520, which 4/5 years old now, struggles to show the map when on the map page.
When I've downloaded a .fit file from, ridewithgps premium account and then ride the course i've downloaded it does give turn by turn alerts but I cannot see the map.
The page has the arrow at the top but most of the time, not all, the map doesn't load up, so at some junctions or when there is a lag with the alert, i can go off course and it's hard to follow.
Seems to happen when i have the standard gps and the gps with glosnass,
Any tips to improve this pls.
