Aera 660 05SEP24 updates not installing

I’ve tried using the Garmin USB cable and FlyGarmin on my Mac. I’ve tried updating via WiFi.  I’ve tried re-installing Software Version 4.00.

When I restart, it’s shows updated and current databases.  After I “Press To Accept” I get “Database Installation Ready, Databases are ready to install. Dismiss, View, Install”.

Then I’m in a never-ending loop and unable to get these databases installed.

Is there a hard reset for the Aera 660?  I own two of them and the other has updated with no problems.

Thank you.
