What to Do When Bluetooth Connects to the Car but There's No Sound?

[Sean]

If the car Bluetooth is successfully paired but there's no sound, it may be because the phone volume or the volume of the car navigation system is not turned on. It could also be that the car system is not on the Bluetooth media audio playback interface and is still playing the last media audio source, resulting in no sound when playing music. Here is an introduction to car Bluetooth: 1. Introduction: Car Bluetooth is an in-car wireless hands-free system designed based on wireless Bluetooth technology. Its main function is to connect with a mobile phone via Bluetooth for hands-free calls during normal driving. 2. Precautions for using car Bluetooth: (1) Do not use it under strong light for too long, as this will affect the lifespan of the car Bluetooth. (2) Do not clean the device with corrosive liquids, as this will damage it. To extend its lifespan, regular protection is necessary. (3) Do not store it in excessively hot places, as high temperatures will shorten the lifespan of electronic devices, damage the battery, and cause some plastics to degrade.
