AVIC 8100NEX

Can a USB Flash drive with Audio files and Video files be connected to this Head Unit?

If so, what is the maximum size the Flash drive can be?

Can one open diff folders from the root directory?

Are the files scrollable via the steering wheel control and the HU?

Thank You !

You should read the specs in the back of the manual. There also lots of info on the number of files/directories and file formats supported. If you don't have a manual, you can download one from Pioneer's web site.
