Does the navigation freeze on the logo, reboot or fail to start? We repair Mercedes-Benz NTG3 Harman Becker fitted in Mercedes S-Class W221 and CL C216 models. Send the removed module with a description of the symptoms and we will check it in our workshop.
NTG3 is the central navigation unit fitted in Mercedes S-Class W221 and CL C216 models from around 2005–2009. It is a module with a CD/DVD drive, located in the front part of the dashboard.
On the label you will find Becker part numbers, for example 7007 HU DVD W221, 7008 HU DVD W221, 7069 DC C216 ECE or 7010 DC W221 USA. The unit may have a single drive or a changer, and the maps are stored on a hard drive.
In your enquiry, include the part number from the sticker and describe what happens after switch-on: logo, reboots, black screen. Send the removed module to the workshop.
What is happening with your NTG3?
The symptoms help describe the fault. We confirm the cause after checking the removed module.
Freezes on the logo
After switch-on you see the logo, then the unit freezes and does not continue booting. This may be a software or memory fault. We check the module and determine the scope of the repair.
Reboots repeatedly
The unit displays the logo or screen and then reboots in a loop until it eventually stops responding. The cause may be a hardware fault or firmware errors. After checking the module, we will confirm the cause and propose a repair.
Does not start at all
The unit shows no picture and does not start, the screen stays black. The fault may be software or hardware related, for example damaged memory or a short circuit after using a booster. We check the module and propose a repair.
We connect the removed module and check its behaviour. After inspection, we confirm the scope of work and the price, and begin the repair after your approval.
Software and memory repair
We remove software faults and check the memory that stores the system. If necessary, we repair hardware components and look for the cause of the fault.
Testing and packing
After the repair we test the navigation and return the module securely packed. We issue a VAT invoice and a written warranty.
Repair or replace the unit?
We repair your unit instead of replacing it with another one. We confirm the scope of work after checking the module.
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
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.

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 NTG3
Answers to the most important questions about NTG3 Harman Becker.
Yes. We determine the cause after checking the module. We repair both software and hardware faults.
After the repair, does the module need coding to the car?
No. The repaired unit does not require any special coding.
What causes such faults in NTG3?
The cause may be firmware errors, memory damage or hardware damage caused, for example, by short circuits after using a booster. We confirm the cause after testing the module.
Do you determine the cause so the problem does not return?
Yes. We look for the faulty component and the cause of the failure so we can propose a repair that reduces the risk of the fault recurring.
Will I be charged for diagnostics if I decide not to go ahead?
No. If you decide not to proceed, or the unit cannot be repaired, or the fault lies outside it, diagnosis and return shipment are free of charge. We only begin the repair after your approval.
