Using Garmin GPSMAP 66st.\nRegarding geocache.com.\nThe Garmin has the the ability to store Premium caches from geocache.com even when a person only has a "basic" account simply by inputting the .gpx code and downloading the info from geocache.com. These remain even when the unit is rebooted. My question is, where are they stored inside the Garmin gps and in what format? The basic .gpx files are stored in the gpx folder however the premium gpx files seem to be stored some place else. Maybe in a different format? Anyone have any idea where?
