I am impressed at the ability to download gpx routes. Of course, it doesn't always choose the route I would have chosen. I wonder if there is a way to tell it to go via a certain city in order to force to go a different way.
I still don't understand the 'insert mark' feature. I think it inserts the current location of the gps. Is there a way to edit or label the marks? How about uploading stored waypoints that I have from a different source? I inspected the marks file that I saved away and it seems like it is written in xml markup. I guess I could write a Perl script on my desctop to generate an xml file that could be loaded.
