I have a 2017 Impala and I have my iPod Touch connected to CarPlay. I listen to audiobooks and I set them up with a playlist. Once I have listened to the books I delete the book and the Playlist from the iPod. However, all the playlists still show up in CarPlay when I hit the playlist button. How do I remove the old playlists. It makes it hard to find the current playlist I want to listen to.
