I have audio books I want to listen too on my phone. It looks like I need iBooks to sync. I can't figure out how. My audio books are in music and that format sucks for books. Any help would be appreciated. I have windows 10.
I’m sorry, but I use macOS, so I cannot guarantee that this will work for you. But, for what it’s worth, here it goes:
It appears that iTunes for Windows can handle adding iBooks and audiobooks to your iPhone.
Follow these steps, but instead of using iTunes 11 as mentioned in that support document, get the latest version of
iTunes for Windows here (the site should automatically detect you’re using Windows and present you with the Windows download link).
Please reply if you need further assistance and I’ll do my best to help you out.
