Why can't I connect to the Bluetooth in my car?

[AlanaRose]

Connection to the car's Bluetooth fails because the mobile device has moved out of the communication range of the car's Bluetooth, and the signal may not be received if the distance is too far. Here is the relevant introduction about car Bluetooth: 1. Main function: Use Bluetooth technology to connect with the mobile phone for hands-free calls during normal driving, so as to free both hands and reduce the hidden danger of traffic accidents. 2. Configuration: In order to promote its Bluetooth technology, eTai Electronics even launched a sophisticated hands-free Bluetooth with a solar charger - Black Diamond. Black Diamond uses rechargeable lithium batteries and is equipped with a special solar charger. The driver can answer the phone without wearing headphones and can use the latest noise reduction technology to reduce the interference of other sounds, showing a strong sense of technology.
