What are the reasons for no sound in the multimedia system of the 2016 Changan Oushan?

[DiCharlie]

The car player has no sound, but the radio works fine, indicating a malfunction in the car player. The car player, also known as the car MP3, consists of two parts: 1. the MP3 module, and 2. the FM transmitter module. The audio from the MP3 is transmitted to the FM transmitter module, which then sends it to the car radio for reception. Therefore, if the player has no sound, the following three areas should be checked: 1. The cigarette lighter socket: Check if the cigarette lighter socket that provides power to the MP3 has normal voltage output. 2. The FM transmitter module of the player: Turn on the player and the radio, adjust the frequency to match, and listen carefully to see if the sound from the radio has significant noise. If there is a lot of noise, it indicates a fault in the FM transmitter module. 3. The MP3 module of the player: If the player and radio are turned on and the radio does not emit noise or the sound is very quiet, it means the FM transmitter module is functioning properly, and the issue lies with the MP3 module.
