Here are the reasons why you can't play music via car Bluetooth: Volume Not Turned On: The volume on the car navigation system or mobile phone is not turned on. Parameter Mismatch: The music playback programming of some mobile phones is incompatible with the docking codes of certain car models, so only calls can be answered but music cannot be played. Operation Error: The multimedia music feature of the car Bluetooth is not enabled. Find the multimedia option on the screen, enter it, and select Bluetooth for music playback. Signal Interference: The media audio on the mobile phone is not turned off, causing signal interference with the Bluetooth function.

I've encountered this issue several times where the car's Bluetooth connects but won't play music, which is really frustrating. There are quite a few common causes: It might be due to improper pairing between the phone and the car's system, such as mismatched device names or residual cache from previous connections. It's recommended to delete the car's Bluetooth record in the phone settings and then re-pair. Also, check the phone's volume settings to ensure it's not muted or the wrong audio output source is selected. Sometimes, the car's system software needs an update, as outdated firmware can cause compatibility issues. Plug in a USB drive or connect to Wi-Fi to check for new versions. Hardware failures like a damaged Bluetooth module could also be the culprit, especially in older vehicles. When I dealt with this myself, I first restarted both the phone and the car's infotainment system, which solved about half the problems. If that doesn't work, it's best to visit a 4S shop or service station to check the hardware components—don't push through it yourself, safety comes first.

Most issues with playing music via Bluetooth are caused by operational errors. First, ensure that your phone's Bluetooth is turned on and the car's display has selected Bluetooth as the audio input source. Many people forget to switch the output to the car's system in their music apps, such as Spotify or QQ Music, leading to incorrect settings. Also, make sure the volume is turned up and not muted. Check if the car's Bluetooth connection is being used by another device, such as another phone or headphones. Compatibility issues are also common, especially with older phones and newer car models. A simple solution is to turn off both the phone's and car's Bluetooth, wait a few minutes, and then restart them. If the car has a factory reset option, you can try that. With a bit of practice, you can avoid similar mistakes in the future.

The issue with the car Bluetooth not playing music may stem from the vehicle's own system. Check if the Bluetooth function of the car entertainment system is activated, as sometimes software bugs or system conflicts can cause unstable connections. Updating the system firmware is a good approach—refer to the vehicle manual for update methods. Hardware compatibility issues, such as weak receiver signals or insufficient memory, can be tested when the vehicle is parked. Don’t overlook the phone settings and ensure no interfering devices are nearby. In practice, I recommend first performing a soft restart of the car device, which can resolve the issue in most cases.
