Just took delivery of a 2012 328i and I have a question. I like to listen to audio books on the ipod. I connected the ipod to the iDrive and can play books but I can't advance through the chapters in the book or fast forward. Chapters aren't in different files like songs but bookmarks in the same file. Does anyone know how to advance chapters in iDrive? I'm betting it can do it and I just don't know how, my other car (not a BMW) does it just fine.
