I have downloaded a GPX file: " Red_Light_Camera-AUS-Western_Australia.gpx". for loading into my Nuvi 660.
In Roadtrip (version 2.0.1, OSX 10.5.6) I select File Import, point to the gpx file, select the file and I get the message: "Red_Light_Camera-AUS-Western_Australia.gpx" could not be imported"
I also tried to load a csv file, but that file type is greyed out when I try to load.
