On my B8 S4 you can open the hidden menu and change the input levels for the FM radio, CD player, BT, etc so you don't have the entertainment system blasting when you switch between inputs.
Since the hidden menu option is gone, does anyone know how to do this with coding? I would like to increase the input level for the attached phone to match the radio.
