Finally, to get the audiobook onto your iPod, connect your iPod to the computer. If your iPod is set up to transfer content automatically (its default setting), the new audiobook content should sync right over. For users who've configured their iPod for manual file management, simply drag and drop the book from the Audiobook section of iTunes and onto the iPod icon.
