Why does the music played by the car MP3 always get stuck? 1. It may be that the player has very high requirements for sound quality, audio encoding, audio channels, sampling frequency, etc., so the downloaded MP3 must meet the requirements of the player so that it will not freeze. Carefully read the instructions and requirements of the player. Just modify it accordingly. 2. It may be caused by a problem with the memory of the player. Just format the memory of the car MP3 and then play it again. 3. It may be caused by a problem with the downloaded MP3 music itself. Just change the download method and try again.
