Had this same aggravating issue w/ my GPSMAP 64S, & was about 10 minutes away from returning it completely for a refund... Simply deleting the GGZ files & then rebooting worked temporarily for one reboot cycle; but after cycling power, all my geocaches would all be lost again as described. I ended up backing up all of my GPX files (waypoints & geocache list) & then deleted the whole entire folder along with the three stock GGZ files completely (some of the 250K caches were out of date anyways & the list was incomplete for my area). Performed a "Hard Reset" after deletion, reinstalled the last firmware update, performed another "Hard Reset" after booting up, & then transferred all the waypoint GPX files back onto the device with the geocache GPX file on the SD card. So far, no problems at all with the device itself (Other than the poor screen resolution that's hard to use for mentally planning a route on the fly & as you are walking in unfamiliar areas). I seriously wish Garmin would lock the cursor in the middle of the screen where moving the curser on the map would cause the map to move (rather than the curser having autonomy until it hits the edge of the window where then you hit zoom & you've lost your sight picture & point of reference, where you then have to zoom back out, scroll back to your location to understand what the heck you're looking at... Love the accuracy of the device in thick tree cover that I often find myself in where my cellphone craps out GPS wise & signal wise; but hate the screen resolution & utterly cannot stand the freely moving cursor as it forces me to sit down & take 2 minutes to figure out what the heck I'm looking at & plan by semi-blind waypoints, all the while my dog & I are getting eaten alive by mosquitos... Garmin needs to come out with a GPSMAP platform device in it's same exact button format w/ the Oregon 600 Screen resolution (minus touchscreen) & a way to lock the curser in the middle of the display... This is what the 64S should have been & I'd gladly pay $500 for it. I'm highly tempted to exchange the 64S for the now $200 62S and wait until Garmin comes out with a worthwhile upgrade (from what I read on the interwebs, many others are in this same boat of thinking...)...
