The reason for no sound when the car audio is connected to Bluetooth is that the volume is not turned on. Here are the relevant details about car Bluetooth: 1. Introduction: Car Bluetooth is a feature equipped in many cars. After connecting a phone via Bluetooth, you can play music from the phone and directly answer calls, which is very convenient. If music cannot be played after connecting the phone via Bluetooth, it means the audio source of the car's multimedia system is not set to Bluetooth. 2. Function: Many cars come with an in-car connectivity system that allows the owner's phone to connect with the car's system, enabling more functionalities. Many cars are factory-equipped with Carlife or CarPlay systems. Carlife is specifically designed to connect with Android phones, while CarPlay is designed for connecting with Apple phones.
Last time I helped my neighbor troubleshoot this issue, and found the most common cause was the audio channel not being switched to Bluetooth. After the car system connects, it shows as paired, but is actually still playing in radio mode. You need to find the 'Audio Source Switch' button on the center console screen and change it from USB or FM to Bluetooth music mode. Also, don't forget to check if your phone's media volume is turned off, as many models have separate controls for call and media volume. If it still doesn't work, reset the Bluetooth settings: first disconnect the historical pairing record, then restart the car system (hold the power button for ten seconds), and finally re-pair. By the way, here's a little-known fact: the lifespan of a car's Bluetooth module is about five years. Older cars may experience disconnections due to chip aging—I've seen an eight-year-old car that only got fixed after replacing the module.
