Had no luck, even with latest firmware, getting the unit to resume any of my audio books. I tried changing the tags on the mp3 files but it did not work. The unit would go into auto shut off and then force you to start your audio book file from the start every time.

Ex Output:
Negative

Doesn't get much better than this. What a blessing I have recieved from Pink's expositional approach to this great King's life.

Ex Output:
Positive

Very disappointed! The book was missing several chapters. Because it was needed for school, we were forced to purchase another copy.
