What are the reasons for no sound when playing music via Bluetooth in a car?

[JudeDella]

Reasons for no sound when playing music via Bluetooth in a car: 1. The car multimedia system volume is not turned on, simply turn on or increase the volume; 2. The mobile phone volume is not turned on, you need to enable the phone volume; 3. The mobile phone and car computer are incompatible, requiring adjustment of the car Bluetooth settings or professional inspection; 4. Bluetooth signal interference, which may occur when there are too many electronic devices in the car or when passing through areas with weak signals. Car Bluetooth allows drivers to avoid the hassle of manually answering calls, reducing the incidence of traffic safety accidents. Additionally, the electromagnetic wave radiation from Bluetooth to the human body is much lower than that from directly holding a phone.
