BMW X1 may have no sound after connecting Bluetooth due to low volume, simply increasing the volume may solve the issue. It could also be caused by damage to the car audio system, requiring timely repair or replacement. Below is a detailed introduction about the BMW X1: 1.

I previously encountered a similar issue with my BMW, and there could be multiple reasons. For example, the Bluetooth connection was successful, but the media volume on the phone was either turned off or set too low. You need to confirm that the audio output in the phone settings is selected as Bluetooth. Secondly, the BMW's onboard system might be improperly configured, such as the audio source in iDrive not being switched to Bluetooth mode—sometimes you need to adjust it in the menu. Another possibility is unstable Bluetooth pairing; try disconnecting and reconnecting, or restarting the vehicle's power and the phone's Bluetooth. Occasionally, the Bluetooth module might have a bug requiring a firmware update, which you can check for using a computer to see if there’s a latest version. Hardware failures are rare, but issues with the speaker wiring can also cause no sound. It’s recommended to first check the phone’s volume while playing music, ensuring it’s the media volume and not the notification volume.
When using the BMW X1, I encountered the issue of no sound over Bluetooth, and I believe the main cause might be user error. For example, after connecting the phone via Bluetooth, forgetting to select the Bluetooth audio source in the iDrive interface can result in the sound being routed elsewhere. There are also many issues with the phone itself, such as the media volume being turned off or the app not having permission to access audio, so reopening the music app to check is advisable. On the vehicle system side, cluttered settings can interfere, such as navigation taking priority over the audio channel. Additionally, Bluetooth version mismatches or outdated phone systems might be the culprit, and upgrading could resolve the issue. A handy daily tip: try turning the vehicle's entertainment system off and on again, or disconnect and re-pair the Bluetooth, which usually fixes the problem.
