Why is there no sound when playing music via Bluetooth connection in the car?
2 Answers
After connecting the phone's Bluetooth to the car's Bluetooth, the possible reasons for no sound when playing music are: the phone's call volume is not turned on; the volume of the car's navigation system is not enabled; or the car's Bluetooth is not properly connected to the phone. Here are some additional details: 1. Precautions: Ensure that the phone's Bluetooth settings are set to 'Visible to All' or 'Discoverable', and also make sure that the car's Bluetooth function is turned on and in a visible state. 2. Reason: The media audio on the phone might not be turned off, causing signal interference with the Bluetooth function.
I often encounter the issue of no sound when playing music via Bluetooth in the car, and I've helped friends fix it several times. The core reason is usually mishandled connection details, such as Bluetooth pairing appearing successful but the audio source not being selected. First, confirm that your phone's music app output device is set to Bluetooth, not the internal speaker. In the car, check the audio settings to ensure the mode is Bluetooth, not radio or AUX. Another common issue is volume—if both the phone and car audio are set too low or muted, naturally there's no sound. Software bugs are unavoidable, especially after system updates; a simple restart of the phone and car system can solve most problems. Compatibility is a hidden killer—older phones may struggle with newer car systems, so check if both devices have the latest software. Occasionally, line interference or module failure occurs; it's advisable to have technicians check the Bluetooth module during regular maintenance. Don't panic—just troubleshoot step by step.
