I don't agree that the crew "has been very open". Release the watch files.
Quick summary on the watch files...
...You can doctor gpx files and upload them to the TomTom MySports website, [/quote]
I don't believe so,no. All uploads are managed for you direct from the watch which uses a proprietary format called ttbin. There is no manual upload option or support for gpx input files, just export. I looked into the whole thing a while ago when I first got mine and before this story blew.
I would suggest we leave it at that since, as the old saying goes, even the walls have ears.
