Having a problem uploading route from a garmin forerunner 405. Route manager sees the device but upload data status stays at 0%
I don't have a 405, but with my 305 that page is retrieving data successfully using Internet Explorer, FireFox and Google Chrome.
Have you tested your Garmin Communicator installation? It looks like it's getting hung up on a step in the Garmin code, before it gets to our stuff.
