Nuvi 1450 +uSD lost US maps when updated with Garmin Express

Hi everyone,

I’ve been using my Garmin GPS in the US for over 7 years, usually updating it every year or so without any issues. Yesterday, it prompted me for an update, so I ran it with the latest Garmin Express on macOS (also fully updated). 

After the update, all my US maps disappeared! Now it only shows Canada, France, and a few other random countries. I've done the update multiple time in the last 24 hours, same results. 

When I bought this GPS, I was told it came with lifetime map updates. Has anyone run into this before or know how to get the US maps back?

Thanks in advance for any help!
My AI assistant, suggest the following but those options are not available in my UI:
  1. Open Garmin Express again and check under “Map Options” → “Install Maps”. Sometimes it installs only a region by default and you need to reselect North America.

  2. If you see only Canada/Europe, Garmin might have defaulted to a different map set (sometimes it swaps regions due to space issues).

  3. Try the “Change Map” option in Express to re-download the US maps.

  4. If they don’t show up, you may need to contact Garmin support to re-enable your “lifetime maps” license—it may have gotten corrupted or unlinked.
