If the Bluetooth music connection is silent, it may be because the multimedia volume on the phone is not turned on. Here is some relevant information about car Bluetooth: 1. Function: After successful Bluetooth pairing, you can use your phone to play audio files or answer calls, which is very convenient. While driving, it ensures road safety. Once the car's system is connected to Bluetooth, you can make calls directly through the car's system in hands-free mode. 2. Automatic connection: Once your phone is connected to the car's system, it will automatically reconnect the next time you use it, provided that the phone's Bluetooth is turned on. This eliminates the need for frequent pairing, saving time and adding convenience to vehicle use. However, when using Bluetooth calls, be mindful of privacy concerns.
