I don't know if this is native to CarPlay itself or my alpine ILX-007 unit. I'm not getting any kind of audible notification for text messages. At first I thought it was because of my Apple Watch, since notifications are forwarded to it and tap my wrist. But no. I turned off my watch as a test. Nothing. Unless I go back to the home screen and see there's a badge, I don't know when a message comes in. Any ideas?
