Why is there no sound after successfully connecting Bluetooth in Audi A6?
2 Answers
The vehicle has not switched the playback source to Bluetooth mode, or the volume on the car navigation system or mobile phone is not turned on. Below is a related introduction to car Bluetooth: 1. Function: Bluetooth/car phone is designed specifically for driving safety and comfort. Passengers only need a Bluetooth-enabled mobile phone to connect with the car Bluetooth, allowing them to make and receive calls through the car Bluetooth. 2. Features: Automatically identifies mobile phones without requiring cables or phone holders to connect with the phone; users do not need to touch the phone (keeping both hands on the steering wheel) to control it, using voice commands to answer or make calls. Users can conduct calls through the car's audio system or Bluetooth wireless headsets.
I've been driving an Audi A6 for four years and have also encountered the annoying issue of Bluetooth connecting but no sound coming out. At the time, my phone clearly showed it was connected, and the car's infotainment system also displayed a successful pairing, yet there was no sound. After struggling for a while, I found the problem was due to multiple device conflicts: my backup phone and smartwatch were both connected via Bluetooth. Turning off the other devices resolved the issue. It could also be due to system lag; restarting the infotainment system by turning the car off and on again might fix it. The key is to check three things: first, ensure the media volume is turned on in your phone's settings; second, check if the car's audio source is switched to Bluetooth; and finally, verify the software version of the car's main unit, as older versions often don't work well with new phones. Once, updating the software immediately solved the problem. If none of these steps work, it's likely an issue with the Bluetooth module's wiring or connection, and you'll need to take it to a shop to check the fault codes with a computer.
