Solution

1. Preparation

Ensure you have the radio code. This can often be found in the owner's manual, on a card, or through your Volkswagen dealership.
Have the vehicle in a safe location with the ignition turned to "On."

2. Enter the Radio Code

Turn on the Radio
- Press the power button to turn on the radio.
Input the Radio Code
- Use the radio preset buttons (1-4) to enter the radio code.
- For example, if the code is 1234, press button 1 once, button 2 twice, button 3 three times, and button 4 four times.
Confirm the Code
- After entering the last digit, press and hold the "Set" or "OK" button (depending on the model) until the radio confirms the code entry, usually by displaying "OK" or similar.

3. Reset Radio Settings

Access Radio Menu
- Navigate through the radio settings using the knob or buttons.
Reprogram Presets
- Manually set your radio presets again as they would have reset to factory settings.

4. Final Check

Test Audio Functionality
- Play a radio station or audio from Bluetooth/aux input to ensure sound is functioning properly.
Adjust Settings
- Set audio preferences including balance, fade, treble, and bass to your liking.
