	Plug your 770 into your PC via the USB cable.
	Go to the filesystem of your 770. On a Windows machine, you can double-click 'My Computer' and look for a drive named 'Garmin Nuvi' (mine's the J: drive, yours will probably be different). Open it up, then go into the Garmin\GPX directory.
	Look for the file called 'Current.gpx' and copy it someplace memorable (like your Desktop).
	In your browser, go to http://www.gpsvisualizer.com . On the main page, look for the 'Get Started Now' box. Next to the 'Upload a GPS file' box, click the 'Browse' button, and find the 'Current.gpx' file you just copied.
