Why is there no music when my Buick is connected to Bluetooth?

[FaithDella]

The reasons for no sound when playing music via Bluetooth connection are: the volume on the car navigation system or phone is not turned on; the music playback program has a different pairing code with certain car models; the multimedia music function of the car Bluetooth is not enabled; the media audio on the phone is not turned off, causing signal interference with the Bluetooth function. Below are specific methods to play music from your phone in the car: 1. USB drive: Download music from the internet and copy it to a USB drive, then connect it to the car's USB port to play music. 2. AUX audio cable connection to the phone: Use an AUX car audio cable to connect one end to the phone and the other end to the car's player to play music. 3. Car Bluetooth connection to the phone: Open the car's multimedia settings and select the [Bluetooth] function. Enable the car's Bluetooth connection function, connect to the phone, and then you can play music from the phone.
