I own a 2014 MDX. While traveling, I listen to audio books on a thumb drive through the USB port. I have carefully labeled each book so that each "disk" is in order so that the book will follow the chapters. However, when the thumb drive is installed in the MDX, it jumbles the order such that the first chapter read might be chapter 18 and then chapter 1 follows chapter 26. What can I do to correct this problem?
