Radio Code Volkswagen Polo IV (9N)

Small round holes around the radio — that's the defining feature of the Polo IV. While later models moved to Torx screws, the ninth-generation Polo still uses the classic DIN removal procedure found on the Golf IV. This article covers everything you need to retrieve the radio code for the Polo 9N.

Small round holes around the radio — that's the defining feature of the Polo IV. While later models moved to Torx screws, the ninth-generation Polo still uses the classic DIN removal procedure found on the Golf IV. This article covers everything you need to retrieve the radio code for the Polo 9N.

Which radio is fitted to the Polo IV (9N)?

VW supplied the Polo IV with three different radios, depending on trim level:

RadioManufacturerTypePeriod
---------------------------------
Alpha 5 (BVX)BlaupunktRadio-cassette2001–2006
Gamma VBlaupunkt / SonyRadio-cassette2001–2006
RCD 200TechniSat / BoschCD radio2004–2009

The Alpha 5 is the entry-level model with cassette and AM/FM only. The Gamma V adds a few extra features but also has a cassette deck. From around 2004, VW introduced the RCD 200 as the first CD radio in the Polo IV.

All three models have a four-digit security code and a VWZ serial number on a sticker on the side of the unit.

How do you know you have a Polo IV and not a Polo V?

Look at the corners of the radio. The Polo IV has four small round holes — two on the left, two on the right — into which a set of removal pins fits. The Polo V (6R, 2009–2017) does not have these holes. On the Polo V, a plastic surround panel conceals Torx screws behind it.

Not sure about the production year? Check the vehicle registration document or look at the sticker inside the door jamb for the build date.

Finding the radio code without removing the radio

The original radio code for the Polo IV can be found in the following places:

  • Service booklet — When the car was new, a small card with the four-digit code was included in the document wallet.
  • Glovebox — A sticker on the inside of the flap or a loose card kept in the wallet.
  • Anti-theft identification card with the keys — Volkswagen supplied this as standard with new vehicles.

Lost it? Then you'll need to retrieve the radio's serial number.

How to find the VWZ serial number

The serial number is printed on a white sticker on the left or right side of the radio, sometimes on the top. The format is VWZ followed by eleven characters, fourteen in total — for example VWZAZ1N6251566.

Unlike some Ford radios, the Polo IV does not offer any way to retrieve the serial number via the display. You'll need to slide the radio out to read the sticker.

How to remove the radio from the Polo IV

The Polo IV uses a DIN cage with round removal holes — exactly the same system as the Golf IV. You'll need a specific tool for this.

What you'll need:

  • VW round DIN removal pins — Product code PC5-133 (Autoleads) or equivalent. Cost: £3 to £6.
  • Alternative in an emergency: two thin metal spatulas or palette knives (handle with care).

Step by step

1
Switch off the ignition and remove the key.
2
Insert the removal pins into the round holes on both sides of the radio. Use two or four pins.
3
Push the pins firmly inward until you feel a click. The pins engage behind the spring clips in the DIN cage.
4
Pull the radio straight forward while holding the pins in place. The radio should slide out evenly.
5
Slide the radio out five to seven centimetres. You don't need to disconnect the cables if you only want to read the serial number.
6
Read the white sticker on the side of the radio chassis. ### Pins in the correct size VW DIN pins come in different sizes. The Polo 9N uses PC5-133 or equivalent round pins. Make sure you buy the right size — pins that are too thick will damage the holes, and pins that are too thin won't engage. The packaging usually states explicitly whether the pins are suitable for Polo/Golf/VW.

How to enter the radio code

The code entry procedure is identical for the Alpha 5, Gamma V and RCD 200.

1
Switch the ignition on. The engine does not need to be running.
2
The display shows "1000". If it shows "SAFE", read the section below.
3
Press button 1 to set the first digit. Each press increases the digit by one (0 → 1 → 2 → ... → 9 → 0).
4
Use button 2, button 3 and button 4 to set the remaining three digits.
5
Check that all four digits are correct on the display.
6
Hold the seek button (right arrow or SCAN) for two seconds to confirm.
7
The radio unlocks and begins to play. Important: You only have two attempts. After two incorrect codes, the radio locks and displays "SAFE". ### Exception: Alpha 5 The Blaupunkt Alpha 5 (BVX) may, in some variants, have a slightly different entry procedure. If the standard method doesn't work, try entering each digit individually and confirming it one at a time. If in doubt, consult the documentation for your specific radio.

Resolving the SAFE lockout

The SAFE message appears after two incorrect code attempts. The radio is temporarily locked as an additional anti-theft measure.

Here's how to resolve it:

1
Leave the ignition on — key in the "on" position, engine off.
2
Wait at least sixty minutes. Some units require ninety minutes.
3
After the waiting period, "SAFE" disappears and "1000" reappears.
4
You now have two further attempts. Do not disconnect the battery. It might seem like a quick reset, but it restarts the waiting timer without clearing the lockout. Simply leave the radio switched on. If the display shows "1 SAFE" or "2 SAFE", these are variants where the number indicates how many incorrect attempts have already been made. With "2 SAFE", the lockout is already active — start the waiting period.

Common mistakes with the Polo IV

  • Trying the Polo V method — The Polo V has no DIN holes. The same applies in reverse: the Polo IV requires removal pins, not a Torx screwdriver.
  • Can't find the sticker — The serial number is sometimes on the top of the radio chassis rather than the side. Slide the radio out further if you can't see the sticker straight away.
  • Confusing Blaupunkt with Sony — The Gamma V was supplied by both Blaupunkt and Sony. The appearance differs slightly, but the entry procedure is identical.
  • Using the code from a replacement radio — If the original radio has been replaced, the code card no longer applies. The code is tied to the serial number of the unit currently fitted.

Ordering a radio code

Frequently asked questions

The Polo IV came with three possible original radios: the Alpha 5 by Blaupunkt (entry-level cassette model), the Gamma V by Blaupunkt or Sony (mid-range cassette), and the RCD 200 by TechniSat as the CD model. Production years run from 2001 to 2009.
The Polo IV uses round VW DIN removal pins, product code PC5-133 from Autoleads or equivalent. Insert two or four pins into the round holes at the corners of the radio, push them in until they click, and pull the radio straight out.
The Polo IV (9N) has four round holes in the fascia for DIN removal pins. The Polo V (6R) has no removal holes, but instead has four Torx T20 screws behind a plastic trim panel. You can identify the Polo IV by the visible holes around the radio.
Use preset buttons 1 to 4 to set each of the four digits. Then hold the seek button (right arrow) for two seconds to confirm. The display shows '1000' when the radio is ready for input. You have a maximum of two attempts.
Leave the radio switched on with the ignition in the 'on' position for at least sixty minutes. The engine does not need to be running. After the waiting period, SAFE disappears and '1000' appears. Do not disconnect the battery — this restarts the waiting timer without clearing the lockout.
