How to set AUX audio on BMW Linux screen
If your car has no sound during use, please enable AUX in the original car system interface.
This product has two sound working modes. 1: Activate sound through the original radio channel AUX. AUX (multimedia) needs to be enabled in the original car system. In the original car system interface, only iDrive operation is supported and touch screen operation is not possible.; 2: Activate sound through original Bluetooth music (this requires your car radio to have this feature). After enabling Bluetooth audio switching in the Linux system settings of the product, connect the phone to the original Bluetooth music to activate the sound.
