I just picked up my new 2012 Blizzard pearl, four, at the dealer's. When I plug in my iPod (Nano, 4th generation if that matters), music works fine, but if an audiobook is selected, the speed is too fast and it sounds like Alvin and the Chipmunks. If it starts with a music track, I can successfully navigate to the book track I want, and it will start where I left off and play correctly. However, when the car is shut down and turned on again with the audiobook still selected, the same problem comes back. I can work around it by manually navigating to a music track before I start the car, but that is a pain. I can also plug the aux cable into the headphone jack and it works fine. I just want the USB/iPod interface to work right. Has anyone experienced this problem. The audiobooks are level 3 audio from Audible.
