I have the above mentioned device (from Costco). Until this most recent software update from Garmin, I could load unlock maps onto it. Now, it tells me that it cannot authenticate the maps and to contact the reseller. I CAN load my older, never locked National Park TOPO maps onto it and those seem to work fine. Which is really all that I need for my hiking trip. But, I would have liked to have been able to have it as a backup device to my other Garmin and have the US City Navigator maps on it as well. Can anyone explain what that error indicates and how to fix it. By the way, I get that error whether I load the maps directly onto the device via USB or onto the microSD card via Garmin Mapsource. Any help is greatly appreciated. We have a six week trip to Montana and Wyoming coming up and I would love to have this thing working before we leave next week. Thanks for any help anyone can provide.
