Stale data doesn't typically cause a device to "stop working."
Can you explain the failure in greater detail?
Well, the device worked okay on days 1 & 2 of our vacation. On day 3, I tried using the search bar to type in locations for destinations. Each time I typed in a destination, the device would simply restart. Oddly, if I went to the menu of recent searches, the device would readily search for those locations without suddenly restarting itself. When I called Garmin tech support, they said the issue was obsolete drivers. They said they could update the drivers but it would cost me $75 to get new drivers (roughly 50% of the cost of a new unit). This feels like a stick-up :(
