2、 The Bluetooth car hands-free system is designed specifically for driving safety and comfort.

Its main functions are:

Automatically recognize mobile phones, allowing them to be connected to the phone without the need for cables or phone trays;

Users do not need to touch the phone (with both hands on the steering wheel) to control the phone and use voice commands to answer or make calls.

Users can make calls through the car's audio system or Bluetooth wireless earphones.

If you choose to make a call through the car audio system, when there is a call or a call is made, the car audio system will automatically mute and transmit voice through the speaker/microphone of the audio system.

If you choose a Bluetooth wireless headset for a call, as long as the headset is turned on, pressing the answer button when there is an incoming call can achieve the call.

The Bluetooth car hands-free system can ensure good call performance and support any manufacturer's built-in Bluetooth module and Bluetooth hands-free profile (compliant with SIG? V1.2 specifications) phones.

In addition, the Bluetooth car hands-free system can also be bundled with global positioning system (GPS) terminals to reduce costs.
