Comand NTG4 is a factory radio and navigation unit made by Mitsubishi, fitted in Mercedes C-Class W204, E-Class Coupé/Cabrio C207/A207 and E-Class W212 from around 2007–2011.
You can recognise it by the retractable screen in the centre of the dashboard and the PCMCIA slot on the front panel. The label may read “Head Unit High ECE Single” or “Head Unit High ECE Changer”.
Describe the symptoms in your request and send a photo of the label or part number if you can. You send only the removed main unit, without the display — we have screens and test looms in our workshop.
The symptoms help describe the fault. We confirm the cause after checking the removed module.
Very loud crackling and “bangs” come from the speakers, and the problem appears once the radio warms up. The cause is a voltage drop across the operational amplifiers in the audio path, which leads to sudden discharge of the coupling capacitors.
The screen works, the navigation shows the map, and there is silence in the speakers or only quiet “clicking”. The complete lack of sound is caused by a fault in the circuit stabilising the power supply to the audio path in the unit.
Customers describe knocking or squeaking even with the car locked and the audio system switched off. We determine the cause after inspecting the removed module.
The unit powers up, shows the Mercedes-Benz logo and keeps restarting in a loop. We also repair this fault, and we define the scope of work after inspecting the module.
The Comand may be completely inactive — black screen and no sound. We inspect the module, diagnose the cause and present the scope of repair.
We connect the removed module to a test bench and carry out diagnostics. After inspection, we confirm the scope of work and the price before starting the repair.
We replace faulty audio-path components with brand-new factory parts. We do not replace the unit with another one.
After repair, we carry out load and temperature tests and return the securely packed unit with a written warranty.
A used unit from the market may have a similar fault. We refurbish your unit, and we confirm the scope of work after checking it.
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
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
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
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 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.

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.

I had a problem with my Audi A3 8V, with no sound from the factory multimedia player. The guys solved the problem in a few days. I recommend them!

Service and expertise 100%. Thank you for helping with my RNS 315 radio. Highly recommended!

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.

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

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.

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 😃
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.
KJAnswers to questions from Comand NTG4 owners before sending the module.
It does not have to be like that. The crackling and popping come from the audio path in the Comand NTG4 unit, so we start by checking the radio.
No. These symptoms have a hardware cause in the audio path, so a software update alone will not remove them.
Yes, we also repair hard drive damage and other unit faults. We confirm the scope of work after inspecting the removed module.
Send only the main Comand NTG4 unit, without the display. Before submitting, you can send a photo of the label with the part number.
No. If you withdraw, the unit cannot be repaired, or the fault lies outside the module, diagnosis and return shipping are free of charge. We only start the repair after you approve the scope and the price.
A sound fault resembling gunshots? OEMatic can fix it.
