3 Answers
Wuling Hongguang has no sound when playing music for the following reasons: Volume not turned on: The volume on the car navigation system or mobile phone is not turned on. Solution: Go to the phone settings - sound, find the media option, and turn up the media volume. The same applies to the car navigation system. Incompatible pairing code: The music playback programming on the phone is incompatible with the pairing code of certain car models, so only phone calls can be made but music cannot be played. Solution: It is recommended to change the Bluetooth playback frequency band to enable normal use. Multimedia music not enabled: The multimedia music feature of the car Bluetooth is not enabled. Solution: Find the multimedia option on the screen, enter it, and select Bluetooth for music playback. Media audio not turned off: The media audio on the phone is not turned off, causing signal interference with the Bluetooth function. Solution: Go to the Bluetooth settings on the phone, turn off the media audio, and keep the phone audio.
Last time my Wuling Hongguang's audio suddenly went silent, I first poked the volume knob to confirm it wasn't turned to zero, then unplugged and replugged the USB drive and found poor contact. Opening the glove compartment to check the fuse box, I discovered the audio fuse labeled F23 had blown. After spending two yuan to replace it, the sound immediately came back. If that didn't work, I would have had to crawl under the passenger seat to check if the amplifier module's wiring was loose—oxidized speaker connectors can also cause poor current flow. Friends who've modified their audio systems should pay extra attention to loose connections or amplifier overload burnout. The final trick is to disconnect the battery's negative terminal for ten minutes to reset the head unit, which works especially well when older car systems act up.
When hauling goods with Wuling, it's common to suddenly lose audio—nine times out of ten, the wrong audio source is selected on the screen! For example, the system might switch to the radio channel even though a USB drive is plugged in. Bluetooth disconnecting from the phone automatically is also a frequent annoyance. You’ll need to manually switch back to the correct audio source mode using the steering wheel shortcuts or the screen menu. Once, I even found the mute button stuck because it was pressed down by a cargo list. If all these seem normal, the main speaker plug on the left side of the trunk might have loosened from vibration—this spot in the Hongguang is particularly prone to shaking loose. For those who’ve upgraded to an aftermarket navigation screen, check if the wiring harness at the back isn’t secured properly. I once short-circuited and burned the amplifier chip on a rainy day because of this.
