How to play music on USB in modern cars:
1. Directly plug the U disk with downloaded songs into the USB interface, open the U disk player, and then you can play the music in the U disk. song.
Note: Currently supports mp3 and wma formats.
2. If there is no USB device in the car, it will not be able to play the songs in the USB flash drive because it does not support USB removable devices.
3. Tip: For cars that support USB devices, just copy the songs directly to the USB flash drive. Do not create a new folder to prevent the player from finding different audio files.
