Why is there no sound when playing music via connected car Bluetooth?
2 Answers
There are several reasons why there might be no sound when your phone is connected to the car's Bluetooth: the volume on the car navigation system or phone is not turned on, the music playback programming on the phone is incompatible with the car model's pairing code, Bluetooth signal interference, or multimedia music is not enabled. Volume on the car navigation system or phone is not turned on: If the volume is not turned on, you won't hear any sound. The solution is to go to the phone's "Settings" - "Sound," find the "Media" option, and turn up the "Media" volume. The same applies to the car navigation system. Music playback programming on the phone is incompatible with the car model's pairing code: Some phones (e.g., iPhone) have music playback programming that is incompatible with certain car models' pairing codes, so you can only make calls but not listen to music. Solution: Try changing the Bluetooth playback frequency band to resolve the issue. Bluetooth signal interference: If the media audio on the phone is not turned off, it may cause Bluetooth signal interference. Solution: Go to the phone's Bluetooth settings and turn off the media audio while keeping the phone audio enabled. Multimedia music is not enabled: Another possible reason is that the multimedia music feature is not enabled on the car's Bluetooth. Solution: Find the multimedia option on the screen, enter it, and select Bluetooth to play music, which should solve the problem.
I often encounter the issue where the car Bluetooth connects but there's no sound, usually due to minor oversights in volume settings. First, confirm whether the phone's volume is turned down or muted, especially since music app volume controls are independent of the system volume. Also, check the car audio's volume—sometimes the system automatically lowers it after Bluetooth connection, requiring manual adjustment. Another possibility is that the audio output isn't switched to Bluetooth—try navigating to the car menu and selecting the Bluetooth audio input option. If reconnecting Bluetooth doesn't work, try restarting both the phone and the car's infotainment system, as this often resolves temporary software conflicts. Paying attention to these small details in daily use will usually solve the problem—no need to worry.
