Notice: some tips you should be known. If there is white noise when you plug 3.5mm audio jack and USB-A port, It because speaker or car audio lack of anti-interference function. ---------but the noise will disappear when we connect the phone. If you found it is poor connection, please use a small iron wire, cotton cloth, alcohol to clean the lightning port of your phone. Maybe it is stuck some cotton wool in the lightning port. It is a normal phenomenon when we use the audio charging cable , because there are two chip running together, they all need be cooling through the aluminum shell. If the USB of the BMW car cannot be charged with the audio charging cable, please use the car charger instead, because the USB of some BMW cars is for U disk. This audio charging cable is only for music and charging, it have no calling function. Tips: Press the button "AUX/CD" or "USB/CD" to switch to AUX mode. Press "MEADIA" button or similar button to switch to AUX mode. Some car need you to long press 3-5 second till you hear a sound of "di" to switch to AUX mode.
