The first step is to make sure the Bluetooth speaker is in pairing mode. Usually, long press the pairing button on your stereo to enter pairing mode.
Second, turn on Bluetooth on your phone and make sure it is unlocked.
Third, find the name of the Bluetooth speaker in your phone's Bluetooth device list and click Connect.
Fourth, your phone will prompt you to enter a pairing code. If the Bluetooth speaker has a display, the pairing code is usually displayed on the screen. If there is no display, the pairing code may be \"0000\" or \"1234\".
Step 5, after entering the pairing code, click \"OK\" or \"Connect\". If the pairing is successful, the phone will beep and the Bluetooth speaker will start playing music.
