Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked in a safe location.
Ensure the vehicle is powered on and in park mode.

2. Check Audio Settings

Navigate to the audio settings on the infotainment screen.
Ensure "Mute" is not activated and adjust the volume to an audible level.
Confirm that the balance and fader settings are appropriately set to the center.

3. Software Update

Go to the "Software" section in the settings.
Allow the system to check for updates and install any available updates.
Restart the vehicle's infotainment system after the update installation.

4. Infotainment System Restart

Press and hold both scroll wheels on the steering wheel until the screen goes black and reboots.
Wait for the system to restart and check if the audio is functioning.

5. Battery Check

Use a multimeter to measure the vehicle's 12V battery voltage (should be around 12.6V).
If the voltage is low, consider charging or replacing the battery.
