Nice tool!
However, I can’t open those tracks in Basecamp/Mapsource, I think Garmin requires a stricter format of GPX, but I dont know exactly how.
I can open those tracks in JOSM, and save it as gpx, but I have to do this for each single track. With several hundreds of tracks this is not possible. Can you write/append all tracks in one single gpx file?
This way I can convert it easier to Basecamp for my Garmin GPS with tools like Javawa’s IMGfromGPX or mkgmap.
