I have the latest TomTom IQ Routes, it is 3 weeks old (Firmware 8.410).

TTTtracklog is starting and is in fact tracking GPS traces in a .gpx file, but only once until you remove the .gpx file. It currently does not append another session to an existing .gpx file.

I want to map a huge chunk of currently not yet mapped soil in central Italy in 2 weeks, so TTTracklog hopefully gets that bug fixed soon.....
