Waypoints on Garmin Explore don't show up in the correct location.

I'm setting up waypoints for White Pocket, Az using gps coordinates from a trusted source, and as I'm creating them the aerial view on Garmin Explore shows the waypoints in the wrong location. Miles and miles away from where they should be. And I see lots of web references that endorse these waypoints so I just don't know whats going on. Any ideas?
