I have 5 decent-size audiobooks loaded onto my Forerunner 255 Music device as MP3s, totaling about 45 hours. Trying to listen to a 10-hour long audiobook MP3 I find that the audio will sometimes jump backwards about 15-20 minutes from when I was listening, though the progress bar (or 'ring') stays the same. For example, I got about 30 minutes into an audiobook, and then it randomly jumped back to about the 15 minute mark, and I had to relisten to the same portion of the book, but the progress bar never moved and progressed from 30 minutes to about 45.
Furthermore, when I try to scrub through the book with the buttons, it skips 0-1 seconds (instead of 30 sec as it's labelled), and if I press the button repeatedly it gets stuck and won't progress at all. Repeated the same word that it is stuck on every time I press the button.
Some info about the device:
- Forerunner 255 Music
- Brand new (maybe 3 weeks old)
- Only about 40% of the device storage is used by the MP3 files
