Why is there no sound when connecting to Bluetooth in a Chevrolet?
2 Answers
Here are the relevant explanations for no sound during Bluetooth connection: 1. Volume not turned on: When the car multimedia system volume or phone volume is not turned on, there will be no sound when playing music via Bluetooth. While playing music, press the volume button on the phone to adjust the phone's volume. Adjust the media volume to the maximum, then adjust the volume in the car. 2. Incompatible pairing code: The music playback programming of some phones is incompatible with the pairing codes of certain car models, so you can only answer calls but cannot play music. You need to change the Bluetooth playback frequency band. If the car Bluetooth multimedia music is not enabled, you need to set it to be turned on.
I've encountered many car owners reporting this issue—Bluetooth is connected but there's no sound, which can indeed be quite frustrating. First, the simplest thing is to check whether the pairing between your phone and the car's system is truly successful. Sometimes the system shows it's connected, but it hasn't actually recognized the audio source. In this case, try turning off your phone's Bluetooth and reconnecting, or switch to another playback source like a USB to see if there's sound, which can help quickly pinpoint the issue. Second, volume settings are often overlooked: make sure the car's volume isn't muted or set too low, and also check your phone's Bluetooth output volume to ensure it isn't too low or switched to silent mode. Another common cause is outdated vehicle software—updating the infotainment system might help. Or, the Bluetooth module itself could be faulty. In such cases, it's best to visit a 4S shop and have a technician diagnose it with professional equipment. Regularly checking these functions during routine car maintenance can prevent minor issues from becoming major headaches, especially for models like Chevrolet, where system compatibility sometimes needs to match the phone's OS.
