Why is there no sound in the car when the phone is connected to the car's Bluetooth?
2 Answers
The reasons why there is no sound when playing music after the phone's Bluetooth is connected to the car's Bluetooth may be: the call volume of the phone is not turned on; the volume of the car navigation system is not turned on; the car's Bluetooth and the phone are not paired and connected at all. The following is more information about car Bluetooth: 1. Functions of car Bluetooth: automatically identify mobile phones, no need for 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 the phone, using voice commands to answer or make calls. Users can make calls through the car's audio system or Bluetooth wireless headsets. 2. How to use car Bluetooth: turn on the car's Bluetooth. After it enters pairing mode, use the phone's Bluetooth function to search for Bluetooth devices and find the car's Bluetooth. Enter the pairing password to complete the pairing.
I've encountered this situation before too—connecting my phone to the car via Bluetooth but getting no sound, which is especially frustrating on long drives. The main issue usually lies in incorrect settings. For example, after the Bluetooth connection is established, the audio might default to the phone's speaker instead of the car's system. You'll need to manually switch the audio output to the car in your phone's Bluetooth settings. Another common problem is volume levels: the media volume on your phone might be set too low, or the car's audio volume knob might have been left at a low level—try increasing both to see if it helps. Also, ensure the car's media source is set to Bluetooth mode, not radio or CD. If the Bluetooth signal is unstable, interference from closed car doors or metal objects could be the culprit; moving closer or restarting the devices might restore the connection. Lastly, check for software updates; older phones may have compatibility issues with the car's system, so updating the firmware or app could resolve it. In short, troubleshoot step by step, stay patient, and you'll likely fix it quickly.
