Hey
This patch allows maemo-mapper to load gpx tracks from a wintec gps.
You have to install gpsbabel to /usr/bin or the menu items won't
activate. The gps needs to be connected to load the log. For a recent
(but not packaged) gpsbabel: http://www.daria.co.uk/gps/
It's a quick and dirty thing and my first real work in scratchbox
(just noticed vim wasn't expanding tabs to spaces, blah).
One reason I wanted to get this out there is so it would be clear
there are downsides to running gpsd. We'd have to stop gpsd during the
track transfer if it was in the loop.
Working with a logging gps can be useful if you want to save the
n800's batteries. I sometimes leave the n800 off and let the gps log
things by itself. The next time I'm hiking I do not want to have to
drop to a shell to pull this off :)
