What is the reason for no sound in Bluetooth music on Hongqi HS5?
4 Answers
The reasons for no sound in Bluetooth music on Hongqi HS5 are as follows: 1. Volume not turned on: The volume on the car navigation system or mobile phone is not turned on. Enter the phone settings and turn up the "Media" volume, and do the same for the car navigation system. 2. Incompatible pairing code: The music playback programming of some mobile phones is incompatible with the pairing code of certain car models. It is recommended to change the Bluetooth playback frequency band for normal use. 3. Car Bluetooth not activated: The multimedia music of the car Bluetooth is not activated. Find the multimedia option on the screen, enter it, and select Bluetooth to play music. 4. Signal interference: The media audio on the mobile phone is not turned off, causing signal interference with the Bluetooth function. Enter the Bluetooth settings interface of the phone, turn off the media audio, and keep the phone audio.
My Hongqi HS5 also encountered the issue of no sound from Bluetooth music before. After struggling for a while, I found that the reasons can be categorized into several types: The most common one is the mobile phone settings issue. Many people don't know that there is a 'Media Audio' option in the Bluetooth settings of the phone, which must be turned on separately. Additionally, the volume controls of the phone and the car's system are separate, so both need to be turned up. On the car's system side, you also need to pay attention: first, click the media icon on the central control screen to select the Bluetooth audio source. Sometimes, if you accidentally switch to the radio mode, it goes silent. Another time, I found that after a phone system update, the Bluetooth protocol was incompatible. Deleting the pairing and reconnecting solved the problem. If the car's system version is too old, there might also be bugs, which can be fixed by upgrading the system at the 4S shop. If none of these work, it might be a hardware failure of the Bluetooth module. In this case, it's necessary to get it repaired as soon as possible, since repairs can be quite expensive. When using it normally, remember to regularly delete unused old device lists to avoid connection interference.
As someone who frequently tinkers with car infotainment systems, I believe troubleshooting Bluetooth audio issues should be done at three levels: The most basic is physical layer problems, such as the phone's media volume being off or muted, or the car stereo volume being accidentally set to minimum. The middle layer involves connection protocol issues, like the phone being simultaneously connected to headphones causing audio interception, or the car system having too much cache requiring a reboot. The highest level is hardware failure, such as a damaged microphone module. Special reminder to Hongqi owners: Pay attention to whether the volume buttons on the steering wheel are stuck - my friend once had fake mute caused by a protective case jamming the button. Also check if 'Allow multiple device connections' is enabled in Bluetooth settings, as this feature may cause confusion. Car Bluetooth is particularly sensitive to phone system versions, with more compatibility issues on Android 12+ or iOS 16. It's recommended to use the original data cable for more stable CarPlay connection.
A friend's car just had this issue fixed the other day, and they summarized a quick four-step self-check method: First, check if the phone's media player is running normally—try switching to a different song. Second, tap the Bluetooth icon on the car's infotainment screen to confirm the connection status; if it shows 'Connected,' click the small gear icon on the right to check media audio permissions. Third, increase the volume on both the phone and the car's system simultaneously, remembering to use the steering wheel scroll wheel for adjustment. Fourth, disconnect and re-pair the Bluetooth—it often works like rebooting a router. If the navigation sound works but music doesn’t, it’s likely a software conflict; force-restart the infotainment system by holding the power button for 10 seconds. If there’s still no sound after trying these steps, it’s probably a hardware issue—don’t hesitate to take it to the dealership for a computer diagnostic.
