1, the first task is to find the power switch on the central control panel, that is, the round key in the middle, press the AUX key after opening it, and the screen display is also in the AUX menu bar;

2. Then click "Device". After clicking' Device', I found that there was no Bluetooth connected device in it. It's empty. When you select Add, the PIN code will appear on the display. Remember this PIN code first;

3. At this time, you need to turn on the phone settings and turn on the Bluetooth function to connect.
