CarPlay already works with Apple Music, Amazon Music and Spotify, so it makes sense that Google would want to get its own service into rotation here. According to 9to5Google, Google Play Music for CarPlay has four main sections. You can view your recommendations on the Home screen, recently played tunes on Recents, your saved music catalog on Music Library and find genres and other collections on Stations. To get this fine feature, you only have to update your Google Play Music app on your iPhone and you'll be good to go. You can also move the Play Music icon to your main CarPlay screen in the CarPlay Settings on your iPhone to make it even easier to access.
