Why is there no sound after successful Bluetooth pairing in the car?

The reasons why there is no sound after successful Bluetooth pairing in the car are: 1. The volume on the phone or the car navigation system is not turned on; 2. The car system is not on the Bluetooth media audio playback interface and is still playing the last media audio source, resulting in no sound when playing music; 3. The Bluetooth driver on the computer is not properly installed. The solution is: Go to the Bluetooth settings interface on the phone, where there are two options: phone audio and media audio. After connecting to the car Bluetooth, both options are turned on by default. You need to turn off the media audio and keep the phone audio, so as to ensure that the three functions of Bluetooth calls, car music playback (or radio), and phone navigation voice announcements do not interfere with each other.
I've encountered a situation where Bluetooth pairing was successful but there was no sound while driving, which was quite frustrating. A common issue is that the phone's volume setting is too low. When I checked my phone settings, sure enough, the music app's volume was only at half. Adjusting it to the maximum fixed the problem. Additionally, the audio source selection in the car's system is crucial. Some cars don't default to Bluetooth mode, so you have to manually switch to Bluetooth audio output in the media menu. If all these checks don't resolve the issue, restarting the phone or the car's system usually does the trick. Last time, my car's software had a minor glitch, and everything worked fine after a restart. Finally, if there's a problem with the speakers or wiring, such as interference or aging, it's best to have it checked at a professional shop. Testing the pairing a few more times when parked can help prevent issues in advance.
