You can do it the way Doc described which works. But if you don't have Basecamp or Mapsource software on your computer it will save it as a .php file. If you have either of the two softwares it will download as a .gdb or .gpx depending on how Doc saved the tracks. It's best to save them to a file on the desktop. Name it whatever. Both extensions will work with the software. EDIT: Magoo just informed me that no matter which of the two sofwares you use it will now save as a .php file. First I knew of this but I'm sure he is accurate.
