Sorry, I didn't imply that the third-party software is able to upload maps to Garmin GPSes. The third party software (such as RouteBuddy
) can upload/download waypoints, tracks, routes, which implies the developers' working knowledge of the USB interface to the GPS.
That's why Mapsource is so critical. They have all the street maps. I'd love to be able to use my Garmin without having to use Mapsource. I just haven't seen anything equal it.
I doubt you'll be able to load Garmin maps with any other software than Mapsource. I know there are apps on Windows for creating Garmin-compatible maps, so maybe something exists, but nothing I've seen for OS X.
