Carplay Navigation Volume
2021 Subaru Crosstrek with latest update and iPhone 11 with latest iOS 14 update. iPhone is connected via USB and Bluetooth.
CarPlay Music playing with volume at an appropriate level. Open Maps, select destination, and then go. Navigation volume then blasts the directions. I have not found a way to lower volume. Volume setting in iPhone’s Maps has no effect.
iPhone 11, iOS 14
