Why is there no sound after successfully connecting Bluetooth in BMW X5?

[AnnaDella]

Here are the reasons why BMW X5's Bluetooth is connected but there is no sound: 1. The phone's sound is not turned on: The call volume on the phone is not turned on. If the phone's media sound is not turned on, naturally you won't hear anything when the phone connects to the car's audio system, which is used for listening to music, making calls, voice control, and other functions. 2. The car audio system is not turned on: The volume of the car's navigation system or integrated unit is not turned on; simply turn it on. If the car's audio system sound is not turned on, you won't hear anything. You can first try connecting through other methods to check if there is sound, to determine whether the car's audio system is damaged. If there is still no sound, it is recommended to send it for repair as soon as possible.
