I have 2011 328xiDrive Sedan with Prof NAV CIC.
I created USB with new MAPs and plugged into glove box USB port and nothing happened. I copied every folder and file under each package folder and placed it in the root directory on the USB. OR Do I need to copy ONE at a time each USB/DVD PKG (4) times in each Part 1 thru 5? That's copy and plug in USB pkg 20 times?
