Why is there no sound when the car's Bluetooth is connected?

[StClara]

The reason there is no sound when the car's Bluetooth is connected is that the media audio on the phone is not turned off, causing signal interference with the Bluetooth function. Below are some related introductions about car audio systems: 1. Introduction: Car audio refers to the sound system installed in the vehicle. The basic requirement for a system to be called an audio system is its ability to reproduce sound. Its anti-interference technology involves using choke coils connected in series between the power supply and the audio system to filter out power line interference, thereby reducing external noise interference. 2. Precautions: The most important aspect to pay attention to in a car CD audio system is dust prevention. The laser head is the most expensive and vulnerable component in a CD player. Although car audio systems are designed with dust prevention in mind, due to varying road conditions, special attention must still be paid to dust prevention. Proper maintenance of the audio system can effectively extend the lifespan of the laser head and ensure the car audio system delivers high-quality music playback for a long time.
