There is a program called Mymotion for pocket pc's that allows you to keep your trail with GPS.
Is that available for the 8310 or any other GPS software that leaves a trail for where you have been?

(this Mymotion can be overlaid in Googleearth...very cool!)

Thanks

So far the closest thing is bbtracker. However it doesn't show map, just trail line. You can export then view it online, however.
