Have a new update to my map in my Ascent, so downloaded to my thumb drive ( PNY USB 3.0 ) I have successfully downloaded the map update before and loaded it into the car. Now after loading the update into the thumb drive, when I try to load the update, I get the response " USB Authentication Unsuccessful). Any ideas what is going on ?

You are possibly trying to downgrade, which isn't possible. Please check your version number in the head unit and let us know what it is.

The confusion is the publication date which is 2019-04-04. The database in the car is the same as the latest update so I am ok.
