Saturday I used my edge 520 to ride the milano sanremo virtual eperience. I downladed the gpx track and start to ride. During the race I watched the quote changed and the tacx trainer followed it with hard or light riding but the maps was always empty and the final result at the end was without any dinamic maps parameters (total positive quote and track followed) pratically my performance saved only with power, heart rate and speed. Did i wrong somthing or this is a limit of function of the edge 520?
Thanks for your response
