Radio Code Ford C-Max I

Family cars and radio code problems go hand in hand. The C-Max I sat on many driveways as the roomiest option among the hatchbacks — seven bags of pasta, a football kit and two child seats all fit inside. But when a car like this changes hands or the battery gives up after ten years of service, the radio suddenly falls silent. Fortunately, the Ford 6000 CD is one of the easiest radios to unlock yourself.

Summary

Brand: Ford
Generation: C-Max I (Mk1)
Production years: 2003-2010
Standard radio: Ford 6000 CD; Visteon
Radio option 2: Ford 4500 RDS; Visteon
Radio option 3: Sony CD; Sony

Which radio is fitted in the C-Max I?

The Ford C-Max I (2003–2010) runs on the same platform as the Ford Focus Mk2 and therefore also shares its radio architecture. Three models are in circulation:

Radio	Manufacturer	Serial number	How to recognise it
-------	-----------	-------------	------------
Ford 6000 CD	Visteon	V-code	Ford logo, traditional buttons
Ford 4500 RDS	Visteon	M-code	No CD player, older design
Sony CD	Sony	V-code	Sony logo on the front

The 6000 CD was by far the most commonly supplied radio in the C-Max I. You'll find the 4500 RDS in the earliest models (2003–early 2004). The Sony version came in higher-spec trim levels.

A practical point: early C-Max I examples (2003-2004) may still have an M-code, while later 6000 CD radios use a V-code. The method for retrieving the serial number therefore differs.

Why is your C-Max asking for a code?

Ford's anti-theft protection is active on all radios built before around 2016. When the power is interrupted — disconnecting the battery, a blown fuse, or removing the radio — the protection is triggered automatically. The display shows "CODE" and the radio will only work again once you enter the correct four-digit code.

How do you find the serial number without removing the radio?

This is the great advantage of the Ford 6000 CD: you don't have to remove the radio to find the serial number. You can retrieve it directly on the display using the front panel buttons.

V-code (Ford 6000 CD and Sony, built from 2004)

Switch the ignition on.

Press and hold button 1 and button 6 together for three seconds.

The radio gives a short beep and shows an information cycle.

At the end the serial number appears — a code beginning with V, followed by six digits.

Write down the full code, including the letter V. ### M-code (Ford 4500 RDS and early 6000 CD, before 2004)

Switch the ignition on.

Press and hold button 2 and button 6 together.

The serial number appears — beginning with M, followed by six digits. ### Lost your code card? Ford supplied a 'Security Code Card' with new cars. Also check these places: - In the document wallet in the glovebox - On a sticker on the inside of the glovebox - In the service booklet near the chassis number entries - Under the boot lining in the boot

How do you remove the radio from the C-Max I?

If you can't retrieve the serial number via the display, you'll need to remove the radio. The C-Max I uses the DIN system with four round corner holes in the front panel — identical to the Focus Mk2.

You'll need four DIN removal pins (type PC5-132, Ford radio removal keys). These are available for a few pounds at car accessory shops or online.

Step by step

Switch off the ignition.

Insert all four DIN pins into the four corner holes (top-left, top-right, bottom-left, bottom-right).

Bend the tabs slightly outwards — this releases the spring clips.

Pull the radio forwards evenly. Apply equal force to all four pins.

Slide the radio out five to seven centimetres to access the label on the side or top. No corner holes but a trim surround? Then the radio is fixed with screws. Remove the trim strip with a plastic prying tool, undo the four screws and slide the radio forwards.

How do you enter the radio code?

Ford 6000 CD

Switch the ignition on — the engine doesn't need to be running.

The display shows "CODE".

Press button 1 until the first digit is correct — each press increases the number by one.

Use buttons 2, 3 and 4 to set the second, third and fourth digits.

Press button 5 to confirm.

If the code is correct, the radio starts up. ### Sony CD or Sony DAB Identical procedure, but with a different confirmation button: - Use buttons 1 to 4 for the four digits. - Press the asterisk (\*) key to confirm — not button 5.

What happens after too many incorrect attempts?

The Ford C-Max I radio allows ten attempts in total. After each incorrect attempt the remaining number counts down on the display. After the tenth mistake the display shows "LOCKED".

With a LOCKED message there is no simple wait-time reset as there is with VW. A Ford dealer or specialist decoding service is then the only option.

Ten attempts sounds generous, but they go quickly. Make sure you're certain of the code before you start — don't guess.

Common mistakes

Mixing up M-code and V-code — Use button 2+6 for M-codes (older radios) and button 1+6 for V-codes (newer radios). Using the wrong method gives no result or an incorrect code.
Noting the serial number incompletely — The letter V or M is part of the code: not 234567 but V234567.
Confirming a Sony with button 5 — On Sony radios, button 5 is not the confirmation button. Use the asterisk (*).
Trying again too quickly after a mistake — The radio offers the option for a new attempt straight after a mistake. Double-check the digits before you enter them again.

Ordering a radio code

Frequently asked questions

The C-Max I (2003-2010) shares its platform with the Ford Focus Mk2 and has the same radios. The most common is the Ford 6000 CD by Visteon with a V-code serial number. Early models (2003-2004) may still have a 4500 RDS with an M-code serial number. Higher-spec versions came with a Sony CD radio.

For the Ford 6000 CD and Sony: press and hold buttons 1 and 6 together for three seconds. After a short cycle the radio displays the serial number — a code beginning with V. For the older 4500 RDS: hold buttons 2 and 6 — this shows an M-code.

Press buttons 1 to 4 to set the four digits, then button 5 to confirm. On a Sony radio you use the asterisk (*) as the confirmation button instead of button 5.

The C-Max I allows ten attempts. After each mistake the display counts down the remaining number. After the tenth incorrect attempt the display shows LOCKED and a dealer or decoding service is required.

With four DIN removal pins. Insert them into the four round corner holes of the front panel, bend the tabs outwards to release the clips, and pull the radio forwards. Identical to the Focus Mk2 procedure.

An M-code (begins with M, followed by six digits) is an older format from before 2004. A V-code (begins with V) is the newer format for radios built from 2004 onwards. For most C-Max I with a 6000 CD, the code is a V-code. Use the correct method: button 2+6 for M, button 1+6 for V.
