What Causes No Audio in BMW 5 Series Bluetooth?
2 Answers
No sound is due to the phone not supporting the music format. Here are the specific steps to connect your phone via Bluetooth to play music in the car: 1. Establish a pairing relationship: The phone and the car's Bluetooth device need to establish a pairing relationship. Enable the Bluetooth function on both the phone and the car's Bluetooth device, and set the phone's Bluetooth to "Visible to all" in the settings. 2. Pair and connect: Search for Bluetooth devices on the phone, select the device once found, and pair using the password: 0000. Once paired, the connection will be successful. 3. Successful pairing: After the car's Bluetooth and the phone's Bluetooth are successfully paired and connected, you can make and receive calls. Playing music on the phone will allow you to enjoy it through the car's Bluetooth device. This method is applicable to all models of Android and Apple systems.
My BMW 5 Series Bluetooth has no sound, often due to pairing issues or incorrect settings. Check if your phone has media audio permissions enabled. For iPhones, you need to select media sharing in the Bluetooth settings, and Android has similar options—without this, sound won’t transmit. Sometimes the iDrive system acts up; restart it by holding the volume knob for 10 seconds to force a shutdown and then turn it back on to refresh the connection. Outdated software can also be a problem—check for updates in the car’s settings, as BMW’s official website often releases new firmware to fix such bugs. Hardware-wise, Bluetooth module failures are rare, but if it’s broken, you’ll need to visit a 4S shop for repairs. If the issue occurs while driving, pull over safely and try re-pairing the device—don’t compromise safety. Bluetooth interference is also common; strong signals from nearby devices can affect performance, so try turning them off or changing locations.
