Update. I've decided that Navio by Tiny Sockets,
http://www.tinystocks.com/gps.html, is better than than GPS Tuner. It provides more information has more options and conforms to the 240 x 240 screen very nicely. The on downside since there is always a downside is that it doesn't appear to save tracks in GPX format. It saves them in NMEA format. GPS TrackMaker which was mentioned above doesn't seem to import NMEA files. The good news is that there is a free utility called GPSBabel,
http://www.gpsbabel.org/, that translates the NMEA to GPX. It also translates many other formats as well.
With Navio running on the 700w to capture the routes to a file, GPSBabel to convert the cpatured file to GPX, and GPS TrackMaker to read the file and interact with Google Earth you have a great combination. Navio is the only package that you must pay a fee to use. The rest are free to use.
Again this is a good solution for hikers or bikers or runners that want to track their routes. Of course if my Ostia software that game with my Pharos GPS would only allow me to track and export routes, I wouldn't need the Navio application.
