Bushnell Backtrack D-Tour

I found something about a software named >>>Fugawi<<< which may be able to read *.btk files.
And this 'Fugawi' software appears to have a Google Earth plugin that is able to export data in *.kml format.

And I read that *.btk file format may be a commercial format. If so, then the authors of the format have their legal rights and surely have their hands on it. And their lawyers may have their eyes on unwanted converter tools.
