Purchased the Garmin 64st early 2020. Used it once. I pulled it out last week and all 250,000 preloaded geocaches are gone. Spent an hour on the phone with Garmin customer service and they couldn't help. Suggested I send it back but because barely out of warranty, I would have to pay $110 to have it replaced and send it back at my cost. This is a known issue and they still refuse to honor the warranty. I've tried everything including a hard reset. I don't have a memory card in it as I only used it when the Boy Scouts went geocaching (which is why I bought it). Now, with all the geocaches gone, it's useless. Looking for any help please.
