Has anyone figured out how to download routes from Microsoft Streets and Trips 2010 to a Garmin 276C. The documentation claims it can do that. It requires installing a plug-in from Garmin, which I did. When I attempt it, it does download to the GPS, but only the Waypoints get downloaded NOT the route. I saw the other post about exporting GPX files and loading them into Map Source, but I was hoping to do it in one step.
