Audible, an audiobooks service owned by Amazon, pushed a major update to its iPhone and iPad application this morning which added CarPlay functionality along with a couple nice-to-have improvements in the app's iOS edition.
After downloading today's update, the Audible app will automatically appear on the dashboard of CarPlay-enabled vehicles and those supporting CarPlay via aftermarket solutions from Pioneer, Alpine and other companies.
As noted by MacRumors, iOS 8.4 has brought another change to the table that's remotely related to the Music app. Audiobooks—a feature that was found in the Music app for firmware prior to iOS 8.4—has been relocated to the iBooks app.
When you download or sync an audiobook to your iPhone, it'll automatically appear in the Audiobooks section of the iBooks app if running iOS 8.4. Audio books feature a small headphone icon to indicate that it's an audio book and not a normal book.
