When I upload .gpx track (export from garmin connect from .fit file), no map or track are shown.
Nothing change with Google or Bing Option.
My System is Win 8 64bit (Intel i7; 8Gb Ram)
Are you connected to the Internet when you run VIRB Edit? Do you have maybe have a firewall active that might prevent VIRB Edit from displaying the map?
There is also a toggle button that turns the map on or off, make sure you have it on.
