What does 'phone' mean in a car?

[VonChristopher]

The 'phone' in a car refers to the car phone. Pressing this button allows your mobile phone to connect to the car's system via Bluetooth, enabling you to make and receive calls through the car's system. Here is an introduction to the relevant knowledge about car phones: 1. Design Purpose: Bluetooth/car phones are specifically designed for driving safety and comfort. Passengers only need a Bluetooth-enabled mobile phone to connect to the car's Bluetooth, allowing them to make and receive calls through the car's Bluetooth. 2. Function: The main functions of Bluetooth car phones are: automatic identification of mobile phones, no need for cables or phone holders to connect to the phone; users do not need to touch the phone (keeping both hands on the steering wheel) to control the phone or use voice commands to answer or make calls. Users can make calls through the car's audio system or Bluetooth wireless headsets.
