Be sure and save the GPS track after marking it.

You can load tracks on the list page to edit name and color.

When you export data to GPX it will include all tracks and waypoints. You can then copy the GPX file over to your hard drive and use it with desktop software like Easygps, Expertgps, Topofusion, USAPhotoMaps, or Google earth.

What desktop software are you using?

 

Use GPS visualizer with Google Earth.Its kind of a add-on that  has has some nice features .
