How to Enter your VW Radio Code
Turn on the radio, if "SAFE" is displayed hold down the mode and scan buttons together until "0000" displays.
To enter the code only requires the use of pre-set buttons 1-4.
Start with button 1 pressing multiple times until the correct first digit is shown on the screen
Next repeat the same with buttons 2,3 and 4 until the correct code is displayed.
If you go past your desired number, keep pressing until cycled past 9 and goes back to 0.
The enter button on VW radios varies on each model but 90% of units are holding the "SEEK" or ">>" button to confirm the code into the radio.
