Generally, this occurs because the volume is not turned on either on the car's navigation system or the . Additionally, some phones have different playback compatibility codes with certain car models, allowing only phone calls but not music playback. The specific reasons are as follows: 1. The volume is not turned on the car's navigation system or the phone: Solution: Go to the phone's 'Settings'—'Sound', find the 'Media' option, and turn up the 'Media' volume. The same applies to the car's navigation system. 2. The multimedia music feature of the car's Bluetooth is not enabled: Solution: Find the multimedia option on the screen, enter it, and select Bluetooth for music playback. 3. The media audio on the phone is not turned off, causing signal interference with the Bluetooth function: Solution: Go to the phone's Bluetooth settings, turn off the media audio while keeping the phone audio on.

A couple of days ago, my friend also ran into this issue. His Territory had no sound after Bluetooth connection, and after struggling for a while, he found it was a volume setting problem. The phone's media volume was too low, and the car's default volume wasn't turned up either, so there was no sound from either end. It's best to first confirm that when the phone is playing music, press the steering wheel volume button to increase the car's volume, and also go into the phone settings to max out the media volume. It could also be that the media audio transfer function was forgotten to be enabled in the phone's Bluetooth settings—just connecting with call permissions won't do. Additionally, for older devices, reconnecting is necessary: delete the old pairing from the car's Bluetooth records, restart the phone, and reconnect—it works wonders. Occasionally, the audio source on the central console might be switched incorrectly; pressing the media button to switch back to the Bluetooth channel will immediately fix it.

connection issues with no sound in cars are quite common, and I've encountered it several times myself. The key is to rule out basic problems first: both the phone and the car's infotainment system should be in Bluetooth discovery mode; ensure the car audio isn't muted; and the music playback status should be active. Sometimes minor system bugs can cause glitches - turning off and restarting the car's head unit usually fixes this. Version compatibility is also important - older Android devices and lower-version car systems are prone to issues, so it's recommended to update both to the latest system. Also check the audio output channel settings in the car system, as some may default to local players. If other phones connect normally, it's likely your phone's settings - try testing with a friend's phone to confirm.

I often help my neighbors with this issue. The most commonly overlooked aspect is the music app permissions on the , such as NetEase Cloud Music being restricted from running in the background. Go to the phone settings to grant Bluetooth permissions and enable auto-start permissions. In the car, confirm whether the audio has been accidentally switched to radio or USB mode, and use the physical buttons to adjust the audio source selection. If the Bluetooth pairing name has changed, it may become invalid; delete the saved device in the vehicle and add the new device for pairing. Check for system updates on the car's head unit, as older versions often have Bluetooth disconnection issues. Insufficient vehicle battery power can also cause electronic system abnormalities; keeping the engine running ensures a more reliable connection. If all else fails, try restoring the factory settings.

This situation is mostly due to incorrect connection logic. When connecting via , media audio defaults to the car's speakers, but the phone needs to authorize the transmission. Based on my experience: while playing media, pull down the notification bar to ensure the media output device is set to the car's Bluetooth; use the car's tuning button to switch the audio source to the Bluetooth icon; check the car's system settings for any mute options. If there's still no sound, open the car's system to delete all historical Bluetooth pairings, and also forget the device on the phone before searching again. Some apps like Himalaya require independent audio channel settings, so manually select the output device in the app's player. After starting, wait 15 seconds for the system to stabilize before connecting for the most effective results.

From a perspective, there are six common types of Bluetooth audio issues. 1. Software glitch: The phone or car infotainment system needs to be restarted to refresh the connection; 2. Permission issue: Ensure the 'Media Audio' option is checked in the phone's Bluetooth settings; 3. Volume settings: Increase the media volume on the phone while adjusting the car audio volume separately; 4. Channel conflict: Press the 'Media' button on the steering wheel to force switch audio sources; 5. Compatibility exception: Older phones should update their systems, and the car infotainment system should update its firmware; 6. Hardware failure: Bluetooth module failure is rare, so test with another phone first. 90% of issues can be resolved by deleting and reconnecting the device. Holding the pairing button to reset the connection is the quickest solution.
