Why is there no sound when playing music via Bluetooth in a Lexus?

There may be several reasons why there is no sound when playing music via Bluetooth in a Lexus: 1. Volume not turned on: The volume on the car navigation system or the phone is not turned on, simply turn it on. 2. Incompatible pairing: Some phones (e.g., iPhone) have music playback programming that is incompatible with the pairing codes of certain car models, so you can only answer calls but not listen to music. You need to change the Bluetooth playback frequency band. 3. Music not enabled: The multimedia music feature of the car's Bluetooth is not enabled, you need to set it to turn on. 4. Signal interference: The media audio on the phone is not turned off, causing signal interference with the Bluetooth function.
I remember being quite anxious when I encountered this situation last time. Don't panic first, it's most likely a minor issue. In my years of driving a Lexus, I've found that Bluetooth audio issues usually boil down to just a few reasons: either your phone volume is off or muted – try turning your phone volume to maximum; the infotainment system's media volume might have been accidentally turned off – try rotating the volume wheel on the right side of the steering wheel; also, after Bluetooth connection is established, you need to manually select the audio output mode by tapping Multimedia-Bluetooth Audio on the center display. If it still doesn't work, try turning off your phone's Bluetooth and reconnecting, or reboot the infotainment system by long-pressing the volume knob for 15 seconds. The technician at the 4S dealership mentioned during my last maintenance that this model occasionally experiences software conflicts – if nothing works, simply press the call button to let customer service remotely reboot the system. Lexus's remote assistance service is really convenient.
Tech-savvy people know such issues require step-by-step troubleshooting. First verify the phone itself plays audio normally – rule out app malfunctions. Then press the phone button on the Lexus steering wheel to access Bluetooth menu, checking if the connection status shows "Media Audio Connected". Pay attention to sound settings in vehicle options – some owners may have accidentally muted it. Crucially inspect the infotainment system's audio source selection; Bluetooth connection alone doesn't guarantee audio channel selection. If all these check out, it might be compatibility issues: iPhone users should forget the device in Settings-Bluetooth and reconnect, while Android needs media audio permissions enabled. Additionally, prolonged infotainment system operation can cause memory leaks – turning off the vehicle and locking it for 10 minutes usually resolves this. No need to rush to dealerships for unnecessary expenses.
