The only thing that worked without errors was a reformat with app only. It seems as though the nav no longer works or the map data is completely missing, which makes sense because it was a reformat and only the app was installed.
If I have current version set to (latest build) in the app and select upgrade version to (latest build), it will still load the correct 3.3 files to the USB in order to downgrade and then reformat to (latest build)?
