Why is there no sound when playing music via Bluetooth in the Sagitar?

[DelJoel]

1. Phone-related issue: It might be that the call volume on the phone is not turned on. The solution is to try dialing a phone number and, during the dialing or call state, press the volume up button on the side of the phone to increase the sound. 2. Car navigation system malfunction: It could also be that the volume on the car navigation system is not turned on; simply turn the volume up. 3. Unsuccessful pairing: Another possibility is that the car Bluetooth and the phone are not properly paired. Carefully check whether the Bluetooth connected to the phone is indeed the car Bluetooth. Additional information: First, the phone and car Bluetooth device need to establish a pairing relationship. Enable the Bluetooth function on both the phone and the car Bluetooth device, and set the phone's Bluetooth settings to "Visible to All" or searchable/open for detection. Then, search for Bluetooth devices on the phone, select the car Bluetooth once found, and proceed with pairing. The pairing password is usually 0000 (some might use 1234). After successful pairing, the connection will be established.
