Selected factory audio systems we work on
OEM car amplifier repair
No sound, crackling, bass dropouts, loud pops, flooding or power surge. We diagnose and refurbish factory BOSE, Bang & Olufsen, Harman Kardon, Logic7, Burmester, Dynaudio and other OEM amplifiers.
Factory navigation repair
Black screen, rebooting at the logo, system freezes, no response, a map fault or communication issue with the car. We inspect factory units integrated with the display, radio and vehicle equipment.
Car radio repair
The radio will not switch on, keeps resetting, loses sound, freezes or stops responding after the battery is disconnected. We help determine whether the fault lies with the radio, power supply, coding or another part of the system.
Radio and navigation
unlocking
The radio asks for a PIN code, blocks functions or will not start after the battery has been disconnected, a module replaced or the car purchased? We help you regain access to the factory unit without guesswork or repeated attempts.
Lorry radio and navigation repair
Factory radios and navigation systems in lorries can also reset, freeze, lose sound or stop responding. We diagnose and repair selected OEM units from lorries.
We repair factory car audio equipment
We specialise in factory-fitted electronics in passenger cars and lorries.
We diagnose OEM radios, navigation systems, amplifiers and multimedia modules that are part of a larger vehicle system: they communicate with the wiring, display, controls and vehicle configuration. That is why, when a fault appears, we do not start by replacing the entire module; instead we identify the cause and repair the subassembly actually responsible for the problem. This lets you keep the original system, its fitment to the car and the factory configuration.
We work with factory audio systems such as Bose, Harman Kardon, Logic7, Bang & Olufsen, Burmester and Dynaudio, as well as selected units from lorries. For symptoms such as no sound, crackling, reboots or freezing, we help determine whether the fault lies in the module itself, the power supply or the coding. We test the removed module at the workshop, and if it works correctly, you know the cause has to be sought in the car. Before you decide on a repair, you know exactly what needs work and how much it will cost.
Mail-in repairs from all over Poland
You do not need to bring the car to the workshop — we help you determine which module to remove and send.
You send just the module — radio, screen, amplifier or another OEM unit — while the car stays with you. If, in the case of a sound fault, it is not clear whether the radio or the amplifier is to blame, we may ask for both units. We then check communication between the modules as well, not just each one separately.
The OEMatic workshop is in Sochaczew. Instead of posting the unit, you can bring it in person by prior appointment. We accept factory equipment only, so before you remove anything, we will check from a photo of the rating label whether it is an original OEM module and not an Android replacement unit.
How does mail-in repair work
step by step?
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.
01
Describe the problem and show the device
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
Not sure whether to remove the radio, screen, amplifier or another unit? We will advise which component to check, how to prepare it for shipping and how to pack the parcel safely.
03
We confirm the fault and quote for the work
In the workshop we carry out diagnostics, confirm the source of the problem and define the scope of work. We send a quote for approval. We only start work after your approval.
04
We repair, test and return
We remove the cause of the fault, test the device and send it back safely packed for refitting. Every repair we carry out is covered by a warranty.

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.
Piotr BrzezinaRating 5 out of 5. GOOGLE REVIEW
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.
John DoeRating 5 out of 5. GOOGLE REVIEW
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.

Professionally carried out repair of a factory VW radio, excellent communication, complete professionalism. May there be more companies like this in Poland.
Sławomir PobłockiRating 5 out of 5. GOOGLE REVIEW
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.

Highly recommended. ZENEC radio after the pin was blocked. Code removed. Radio works, old pin. Fast, 1 day. Telephone contact without any problem. Parcel safely packed.
Stefan NowakRating 5 out of 5. GOOGLE REVIEW
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!
Łukasz PuziakRating 5 out of 5. GOOGLE REVIEW
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 😃
Miroslaw SytyRating 5 out of 5. GOOGLE REVIEW
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.
KJCar electronics repair begins with identifying which module is actually causing the problem. In a modern OEM system, a symptom seen in the cabin does not always point to the radio being at fault, because the issue may lie in the display, amplifier or device memory. The key is to confirm the cause before repair or replacement, because in integrated systems a random swap can complicate diagnostics and matching the module to the system. That is why we check original radios, navigation units, amplifiers and multimedia units with the aim of preserving their factory configuration.
What are the typical symptoms and how do we diagnose them?
Typical symptoms can be divided according to whether the problem concerns sound, start-up, picture, navigation or access lockout. This matters because a similar effect in the cabin may be caused by the radio, a separate display, the amplifier or the start-up memory. Signs of a fault may include:
- no sound, crackling, loss of bass or loud pops,
- a radio that will not switch on, goes off or resets,
- a black screen, rebooting at the logo or no touch response,
- problems starting navigation, the map or the data carrier,
- a request for a PIN code or a function lock after incorrect attempts.
We begin diagnostics by confirming which module needs to be checked on the bench. The part number, connector type, hardware version and whether the system has a separate display or amplifier all matter. We then check the power supply sections, how the unit starts up, signs of damage and the functions available during bench diagnostics — that is, outside the target system, at the work station. If the symptoms depend on a specific function, we also assess communication with the panel, display or other system components on the test bench.
Why is repairing the factory module more beneficial?
Repairing the factory module is more beneficial when the problem concerns electronics, memory, power supply or connections, rather than extensive board damage. In practice, this allows compatibility with the display, steering wheel controls, camera, amplifier and vehicle bus, if the given system uses it. This is especially important in integrated systems, where simply swapping the unit does not guarantee full functionality.
A replacement module may only start partially or may require additional coding. That is why whether repair is worthwhile or replacement is needed can only be decided after an expert assessment. It is also important to distinguish unlocking the unit from repair, because a PIN request does not rule out a simultaneous memory or power failure. If the radio or navigation system freezes at the same time as the lockout, the electronics condition is confirmed first.
How does the car electronics repair process work?
The process begins with confirming which OEM module, meaning the factory system component, is actually causing the symptom. We check the part number, hardware version, connector type and system architecture so that we do not repair the wrong item. This is especially important when the radio works with a separate display, amplifier or navigation module. The removed module is assessed, not the whole car.
The unit is then subjected to bench and functional diagnostics. This means we check the power supply sections, how the unit starts up, signs of damage and the functions available during bench diagnostics. Depending on the design, we also assess communication with the panel, display or other system components on the test bench. This makes it easier to distinguish an electronics fault from a problem with the system start-up itself.
Once the cause has been confirmed, only then is the scope of repair and the cost for approval agreed. The assessment itself and confirmation of the cost can take from 1 to 5 working days from receipt of the parcel, depending on the type of unit, the symptom and the complexity of the fault. After approval, we repair the damaged sections according to the accepted quote, and finally test the unit before returning it. Repairing your own module makes sense when stable operation is restored after testing without affecting the factory configuration.
What should be prepared before sending the unit for repair?
Before sending, prepare a description of the fault symptoms and the device identification details. The most useful information is when the problem occurs, after what event it appeared, and whether it affects sound, picture, start-up or communication with the car. Before sending, prepare:
- the car make, model and year,
- a photo of the front of the unit and the label with the part number,
- information on whether the system has a separate screen, amplifier or navigation module,
- a description of whether the fault appeared after disconnecting the battery, water damage, a power surge, an update or replacing a part,
- the wording of any error message, PIN request or lockout, if one appears.
It is not worth making random attempts to enter the PIN or repeatedly connecting an unchecked module. Such actions can trigger a lockout and make it even harder to identify the original fault.
In the request, you must also clearly state that it is a factory OEM unit, because the workshop does not cover Android replacements. If you are not sure what to remove, a good practice is to send photos and a short description first. An initial, free assessment based on photos and a description is prepared within around 24 hours, and the unit itself is sent only after it has been accepted.
Frequently asked questions
and answers
Key information about diagnostics, shipping, quoting and repair of an OEM factory unit.
Which devices do you repair, and which do you not?
We repair factory OEM radios, navigation systems, audio amplifiers and multimedia modules from cars and lorries. We do not repair replacement units fitted in place of factory equipment, including radio-navigation units with Android systems.
Do I need to bring the car to the workshop?
No. You send the module only, and we help you identify which item to remove and how to secure it for transport. You can also deliver the unit to the workshop in Sochaczew by prior arrangement.
How do I know whether my unit is factory fitted?
Check the nameplate sticker: it should have the manufacturer’s logo, e.g. Harman Becker or Bose, and the part number. No brand name or Chinese characters on the label usually mean a replacement. If in doubt, send a photo of the sticker and we will verify it free of charge.
Will I know the cost before I send the unit?
Yes. Based on the photos and description of the fault, we prepare a free, no-obligation initial quote, and if there is not enough information, we ask for more. You send the unit only after accepting it, and we confirm the final scope of work after inspection.
Do I need to know the radio model to ask about repair?
No. Provide the make, model and year of the car and attach a photo of the unit’s panel and nameplate sticker. If the part number is needed, we will ask for it.
Does the unit need to be recoded after repair?
We repair the original module assigned to the car, so in the typical case it retains its factory configuration. If a given model requires additional steps, we will inform you before the repair.
What warranty covers the repair?
Every repair we carry out is covered by a warranty. Its period depends on the unit and the scope of the service and is stated on the invoice in the notes field. The warranty does not cover faults caused later by flooding, moisture or incorrect installation.
