All of my audio books have loaded into the Music slot.  Although shuffle is off, the chapters are all shuffled.  Please help!

move the audiobooks into the podcast folder on the internal memory. you should have better results after you do that. 

You may still have problems in podcast if the title of mp3 file  has  1, 2, 3,  and not 01, 02, and 03.   You may get  1, 10, 11, … 2, 20,21.  

I have an update.  Move the file from one section to another using Explore and the Fuse+unit will sort the file using the file name.  This will cause the file to play in reasonable order.  If it is in Podcast move it to music and then back again.
