Just in time for the new (no handheld devices while driving) law's July 1 effective date, the June update to the Libby app for OverDrive downloadables included features to help some automobile drivers stay hands-free while they listen.
"Libby is now compatible with Apple CarPlay and has improved support for Android Auto. This makes listening to audiobooks while driving easier and safer than ever. Apple CarPlay is supported by every major automobile manufacturer, and now Libby can be your travel companion on road trips or help you combat those daily bouts of rush hour traffic."Source: OverDrive blog
Just remember to park if you want to check out and download a new audiobook.
