What to Do When Lexus Has No Sound When Playing Music?
2 Answers
1. Navigation: Check whether the power supply of the vehicle's DVD navigation or the display screen in the center of the control console is functioning properly. You can first turn off the power and then try restarting it. 2. Steering Wheel: Determine if the car is equipped with a multifunction steering wheel. Generally, there is a mute function on the multifunction steering wheel; check if this button is turned off. 3. Sound: Check if the sound option on the display screen is turned on. Alternatively, it might be due to a temporary interruption of signal input caused by answering a Bluetooth call. In this case, simply wait for the Bluetooth call to end, and the signal will automatically restore, allowing sound to return to normal. 4. USB Drive: If using a USB external playback device, check if the USB drive is loose and not receiving a signal input. If using Bluetooth input, check if the Bluetooth connection from the phone is disconnected.
I also encountered a similar issue when I first drove my Lexus. It might be a source problem, like not switching correctly to Bluetooth or USB mode. The phone connection was unstable, and the Bluetooth pairing was lost. Also, the in-car volume setting was too low, or the steering wheel mute button was accidentally pressed. There might be an incorrect audio output option in the system settings menu. Try restarting the infotainment system a few times, or turn off the vehicle power and restart it once. If none of these work, it's recommended to check if the audio cables are loose or if a fuse is blown—look in the engine compartment fuse box. If all else fails, take it to the dealership and let the technician check the system fault codes with a diagnostic tool. Avoid disassembling it yourself to prevent damaging parts and voiding the warranty. With some troubleshooting, this issue can usually be resolved.
