First of all, make sure that your vehicle is equipped with a sound system that supports USB flash drive audio playback. Then, follow these steps:
1. Insert the U disk into the USB interface of the vehicle. Generally speaking, the USB interface is located on the center console or audio panel in the car.
2. Turn on the sound system of the vehicle. The system will automatically detect the inserted USB flash drive and start playing the music files in it.
3. Adjust the volume. Most car audio systems are equipped with volume knobs or buttons, which you can use to increase or decrease the volume.
4. Change the track. Depending on the sound system, you can use buttons, knobs or touch controls on the screen to switch between different tracks or folders.
5. Confirm other settings. You can also use the menu or setting options of the sound system to further adjust the sound effects, such as equalizer and sound stage mode.
The specific operation steps may vary depending on the vehicle model and sound system. Please refer to your owner's manual for accurate operating instructions.
It should be noted that these steps may only be applicable to general audio systems. If your vehicle is equipped with a special audio system or customized USB flash drive audio settings, you may need to refer to the relevant user manual or consult the dealer for more accurate information.
