Recently attempted NAV update using the $44 thumb drive. How can I tell if it updated successfully, is there a way to check which version using the Nav app? What is the most recent version of North American NAV?

 

The most recent version currently available is NA 2 20

 

Sync Settings>>About Sync. You should get a screen that looks like this. As said, NA 2 20 is the latest.

 

Thanks, well explained.
