What is the reason for the Passat's Bluetooth being connected but no sound when playing music?
2 Answers
The reasons for the Passat's Bluetooth being successfully paired but having no sound are as follows: 1. Check if the phone volume is turned off: Please turn on the phone volume, then check if the car navigation system's volume is turned on, and also verify if the phone is properly connected to Bluetooth. 2. If the above is not the issue: Some car Bluetooth connections may still play the last media audio source if the car is not on the Bluetooth media audio playback interface, resulting in no sound when playing music. 3. It is recommended to switch the car to the Bluetooth media audio interface before connecting the phone's Bluetooth: If only the music has no sound, it cannot be ruled out that certain versions of certain apps may have issues. It is advised to update all apps to the latest version or try using other apps for comparison.
I've encountered this issue before, and it was quite frustrating. When Bluetooth shows connected but there's no sound when playing music, the most common causes are either the phone volume being too low or the car's infotainment system being muted. You can try adjusting the volume using the steering wheel controls and checking the multimedia volume slider on the central display. Another easily overlooked point is that after successful Bluetooth connection, you need to manually switch to the Bluetooth audio source. In the Passat's multimedia system menu, look for the 'Media Source' option and select Bluetooth. I once assumed it would switch automatically, but it was still in radio mode. Also, check your phone settings - some apps may not have audio permissions enabled, which can cause this problem, especially on Android phones where you need to allow media audio in the app permission management. Finally, restarting both the car's infotainment system and your phone often works well when there's a system cache error.
