I just received my 2013 Fit Sport Navi. When my iPod is mounted thru the USB port all of the music files play fine but any audiobooks (longer files) play at double speed. All files play fine thru the AUX jack, but I would rather not have to switch back and forth between the two. Anyone else having this issue? Is there a fix or work around? I don't have any problems with this iPod in my '08 Mini so I am assuming this problem is with the Fit.

 

There's a way to speed up/slow down audiobook files on the iPod. sounds like that's engaged.
