How to fix no sound issue in BMW X3 audio system?
1 Answers
First, check if the power supply to the car audio's CD player is functioning properly. When powered on, the indicator light should be lit, and the CD compartment should open and close normally. If the display is lit, use the interference method to touch the center shaft head of the volume controller. If there is still no sound, it indicates a fault in the pre-amplifier or power amplifier stage. Check if the car audio's output audio cables have come loose. It's best to visit a professional car audio repair shop for a comprehensive inspection.
