Tracks are stored on the SD card, if you have the “Log Track to Data Card” option ticked in the card setup. That is how I use track data to edit OSM - take the SD card out and copy the GPX file off with a card reader.

I downloaded the Mapsource version as per Vclaw’s reply, and have got the map open in QLandkarte. I can create waypoints with it, but it doesn’t seem to be possible to create any tracks or routes with it.
