Finding the Serial Number on a Transporter (T4, T5)'s Radio
The only thing you'll need to get the code is your radio's serial num. (not part number!).
On all VW's, you can find it in one of these places:
- Displayed on the radio screen (by using some combinations of buttons)
- On the radio body itself - you'll need to extract it and write down serial (which is not as hard as it seems).
Search for something that looks like: Serial Num., SN, S/N, Serial, Serial Number...
1. Viewing Transporter (T4, T5)'s S/N on the Display

Step 3: Then unscrew the radio brackets.
Step 4: Carefully pull the radio forward partially (Be careful not to damage the cables).

What is a Radio Code and Why is it Important?
When the radio is cut off from power, it immediately locks and requires an unlock code to be entered before it can be operated.

This system ensures that a removed radio becomes useless without the correct code.
Entering the valid code restores full audio and infotainment functionality.
