Just purchased the Nuvi 500 and was quite impressed with what it can do. Am using it to locate the caches and then "switch over" to my "60" for the final 50 ft.
The problem I'm having is that when I connect the Nuvi to my PC, locate the Garmin\GPX folder and then load the .GPX file with the caches I want to search for, when I then query "Geocaches" it returns a "No Geocaches Loaded" message. By loading, erasing, reloading I have occasionally managed to get the info into the Geocache section but more often than not, I find it under "Favorites" instead.
The "Manual" is quite "sketchy" about loading, saying just to put the info in the Garmin\GPX folder ...
Comments, suggestions ??
