Why is there no sound when Bluetooth is connected to a Volkswagen car?
2 Answers
The following are the reasons why there is no sound after connecting to the car's Bluetooth: 1. The volume on the car navigation system or mobile phone is not turned on; In this case, you can turn up the "media" volume, and the same applies to the car navigation system. 2. Incompatible pairing code: The music playback programming of some mobile phones (such as iPhone) is incompatible with the pairing code of certain car models, so only phone calls can be made but music cannot be played. 3. The multimedia music function of the car Bluetooth is not enabled: You can find the multimedia option on the screen and select Bluetooth to play music. 4. The media audio on the mobile phone is not turned off: This can cause signal interference with the Bluetooth function.
When driving my Volkswagen, I encountered a situation where the Bluetooth connection was normal but there was no sound, which could be due to various reasons. The most common issue might be the volume settings, where the phone's volume is too low or the car audio volume was accidentally turned down to the minimum. Another possibility is an unstable Bluetooth connection, where signal interference causes data transmission interruptions, especially in parking lots or when moving at high speeds. On the hardware side, a malfunctioning Bluetooth module could also be a factor, possibly due to internal contact oxidation or burnout. I recommend first checking the volume controls on both the phone and the car audio to ensure they are not muted; then try re-pairing the devices. If that doesn't work, check if there are any pending system updates. Regular maintenance of the car's infotainment system can reduce such issues. Interruptions in music or navigation while driving can be dangerous and should be addressed promptly. If hardware issues persist, it's best to have them checked at a professional shop. Don't underestimate this fault, as it could affect driving safety.
