Do you see “Enter Security PIN” or the message “System is locked” on the screen? The radio lights up, but navigation, Bluetooth and sound do not work. We unlock and repair the Suzuki PS-4270B Clarion radio from the Suzuki SX4 S-Cross II. Send the module only, and we will check it in the workshop.
PS-4270B is a factory-fitted Clarion radio installed in the Suzuki SX4 S-Cross II from 2022. It is available in European versions with 1.4 Boosterjet Hybrid and 1.5 Dualjet Hybrid engines.
On the white label on the top of the casing you will find Clarion M/N PS-4270B markings, plus Part Number 63T3 and OEM PN 3A102-63T30. The label is visible once the module has been removed from the centre console.
In your enquiry, describe what you see on the screen and when the fault appears. You can send a photo of the label before dispatch. Send the removed module only to the workshop.
What’s happening to your PS-4270B radio?
The symptoms help describe the fault. We confirm the cause after checking the removed module.
Displays Enter Security PIN
The screen shows the numeric keypad for “Enter Security PIN” and the radio plays no sound or connects via Bluetooth. We explain the cause after checking the module and read the original PIN code.
Wrong PIN — last attempt
After a few incorrect entries, the radio shows a last-attempt message. We check the condition and, at our workshop, can reset the attempt counter and restore the ability to enter the PIN.
System is locked
The radio displays “System is locked. Contact your dealer” and does not respond to touch. After checking the module, we carry out the unlock and restore access to the functions.
No sound from the radio
The screen and menus work, but there is no sound from the speakers via FM, Bluetooth or USB. We check the module and repair the fault at electronics level.
Screen freezes
The screen may freeze or not respond to touch. We check the module and propose the repair scope after diagnostics.
You do not need to bring the vehicle in. Describe the problem and we will help you work out what to remove and send. After inspection, you will receive a quote for approval — only then will we start work.
Write what is happening in the vehicle, state the make, model and year. Add a photo of the device, the error screen or the nameplate sticker, if you have one. On that basis, we will initially assess whether we can help.
02
We will help you work out what to send

03

Many thanks to the entire OEMatic team for repairing the radio in my Lexus CT. Professional and reliable service. I can wholeheartedly recommend this workshop! Problem: black screen, no working radio, no interaction with the radio at all.

Highly recommended! My OEM JBL amplifier from a Toyota (CHR, 2017) suffered a short circuit, and other audio workshops would not agree to repair it. Here the problem was solved extremely quickly. They received the parcel on Monday, and by Thursday the repaired unit was back with me. Excellent communication at every stage, and most importantly – the price includes a 24-month warranty. Complete professionalism!

A service absolutely worth recommending. After years of problems with the infotainment head unit in my Skoda Superb constantly freezing and resetting, the MIB was finally repaired. The main dealer could only offer a replacement with a new unit for 3500 eur (!), other car audio companies could not help, and OEMatic carried out the repair in 1 day.

I recommend them wholeheartedly….I don’t know how they did it, but they decoded the radio from an Iveco Daily 2020 faster than it takes to pack the parcel with the radio…One workshop promised a lot, but failed and said the radio was only fit for scrap. I highly recommend them — complete professionalism and a good price. Best regards.

I can definitely recommend them. Mr Tomasz repaired my BOSE amplifiers, RNS, NTG navigation units and more. Always 100% successful, fantastic customer approach and a convenient online platform for placing repair orders.

I recommend OEMatic — only 3 days passed from sending the radio to the workshop and having it fitted back in my car. The radio from a Mercedes ML W164 2007 NTG2 BE 6089 had its fault diagnosed extremely quickly, and the repair was carried out just as fast. Communication with Mr Tomasz was excellent, and updates from the workshop on the progress of the repair were sent promptly. This is definitely a workshop other people can learn from. An obvious 5 stars from me.

VW Touran radio, I sent it to the company because the reversing camera was not working and the radio would not turn on. Sent by courier. Diagnosis: no faults. (the fault needs to be looked for elsewhere) The radio was sent back quickly and the company did not charge anything, not even for the return postage. There probably aren’t many honest companies like this left here in Poland. Many thanks.

Definitely recommended. Very fast repair and very good, speedy communication. Information was available at every stage of the repair request process — an online repair management system. The unit (radio) was already meant to be written off and replaced with another used one. Fortunately, I accidentally found the OEMatic blog while looking for a replacement, and it saved me from replacing it with another used unit, which would have been a loss for the appearance (the fronts of the replacements I found were not in such good condition, and all of them were older than my unit from pre-facelift models); the newer ones were more expensive than the repair. So that’s a plus too.

RNS 315 radio with faulty Bluetooth. The radio sounds better than new. Others gave up on the repair, OEMatic handled it efficiently and quickly without any problems. We need more professionals like this. Thank you for the repair.

I left a Honda Jazz radio panel for repair. In addition to the radio, the guys also repaired the CD player at the same price, even though I hadn’t asked them to. I also received spare bulbs for the button backlighting. Very friendly and professional, the radio and player work flawlessly. I recommend them with a clear conscience. Such expertise is rare nowadays.

For a long time I’d been battling an annoying problem in my VW Passat B8 — the car radio kept losing sound. Fortunately, I found OEMatic Car Media Lab and it was a perfect choice! From the first contact it was clear there was professionalism and huge knowledge of factory audio systems. Quick diagnosis and an even quicker (and most importantly: EFFECTIVE!) repair! The result? The radio plays crystal clear, with no dropouts or interruptions. You can tell the fault was removed at the source, not just temporarily masked. If you have any problems with factory audio, navigation or the radio in your car (especially VW, Audi, Skoda!), I definitely recommend OEMatic Car Media Lab. True experts!

The Harman-Kardon amplifier in my BMW F33 was flooded, so I decided to hand it over to OEMatic. A quick check to see whether it could be saved — yes! it could! A few days later the amplifier was back with me after repair.
For a moment I also had doubts whether only the amplifier had been damaged by the flooding, because I lost the ability to set the time and information such as instant fuel consumption or average fuel consumption disappeared; after a phone call I was told that this can happen because of a break in the car’s CAN circuit due to the amplifier being absent.
The theory proved correct, and fitting the already repaired amplifier helped and all the functions returned.
I hope the amplifier will serve for a long time to come and without faults.
I honestly RECOMMEND IT!

A great company, they will help you in any situation when it comes to navigation. Two companies from the Małopolskie region where I live suggested replacing the unit; at the authorised service centre the fault repair would cost 1400 ,- and they helped me fix it, and over the phone 😃

The content of the reviews I read quickly convinced me to have my unit repaired at OeMatic. I expected the highest quality of service at every stage and that is exactly what I received. After the phone call I received all the information needed for shipping by text message. As soon as the workshop received the parcel with the radio, I got a phone call, we agreed the details, I confirmed the price and the repair began. In the afternoon of the next day I was informed that the repair had been completed, I settled the bill and the radio was back with me after 4 days. It seems there is no room for even the slightest shortcoming in this company (such as a delay with a text message). For me, this is the highest quality. Thank you very much for the repair and I wish you success🙂

Professional and reliable service. The fault was initially diagnosed remotely, and the repair cost estimated. The unit was delivered to the workshop and collected remotely by courier. Everything was fast, straightforward and efficient. The car audio came back to life 🙂 I can recommend them with a clear conscience.

Five stars is not enough.. OEMatic solved the problem with a non-working USB port (motherboard repair) in the factory navigation system from a Kia Sportage in express mode. Highly recommended.

Before you send your PS-4270B Clarion
Answers to questions about the PIN code and PS-4270B radio repair.
The radio has anti-theft protection. A power interruption, battery replacement or moving the radio to another car will trigger a PIN request.
What happens after an incorrect PIN is entered?
After several wrong attempts the radio limits the number of tries, and once they are exhausted it displays “System is locked”. In the workshop we reset the counter and unlock it.
Where can I find the radio PIN code?
The PIN code is in the vehicle documentation from the dealer. If you do not have it, we will read the original code in the workshop and put it on the invoice.
After unlocking, does the radio need to be paired to the car?
No. We read the original code for your radio, and the radio itself does not need to be coded to the car.
Will I be charged for diagnostics if I decide not to go ahead?
If you decide not to proceed, the unit cannot be repaired or the fault is outside the module, diagnosis and return are free of charge.
“Enter Security PIN” on the Suzuki S-Cross screen? OEMatic reads the code and unlocks the Clarion PS-4270B radio — 246 zł, 1 day, no visit to the authorised dealer.
