First, please make sure that CarPlay is available on your car radio. Also install the Digital Concert Hall app on your iPhone and register or log in. If the app is already installed, please update it if possible. Important: to be compatible with CarPlay, iOS 14 or higher should be installed on your iPhone. As soon as your iPhone is connected to your car via CarPlay, the Digital Concert Hall app will automatically appear on the display of the car radio. To keep mobile data consumption low, we recommend using our offline mode.
