Greetings. I am having a problem with my previously-reliable 2460LMT. It no longer can find the U.S., or any state or city in the U.S. Searching on a city name or airport gives me matches in Canada and Mexico. I have the latest map in stalled - City navigator North America 2024.10. The problem began after our internet provider experienced an outage while I was updating the device (via Garmin Express).0 I suspect a corrupted file or directory, but have no idea which it might be. Does anyone have any suggestions on what to check? This is a discontinued model, so Garmin tech support isn't available.
