Comand NTG4 and NTG4.5 – several manufacturers, one enquiry
Units in this series came from different factories, so the manufacturer of your Comand is not obvious. You do not need to identify it yourself. A photo of the front and the sticker with the part number is enough, and we will ask about any missing details. The sticker also shows whether you have a factory module or an Android replacement – we do not repair such replacements.
Symptoms that may indicate a fault in the unit
In Comand NTG4 and NTG4.5 units, we deal with, among other things, such problems:
- no response to the power button, black screen and no sound from the speakers,
- repeated resetting to the logo after turning the key,
- the system freezing and not responding to buttons,
- complete loss of sound or crackling like knocking, immediately or some time after start-up,
- a drive that does not recognise CD / DVD discs, ejects them on its own or jams a disc in the mechanism,
- damaged SD card slot or faulty hard drive.
A separate group is units that have been flooded or dampened. Corrosion in such a unit progresses quickly, so mention it in your enquiry.
What we agree before repair
We check the removed module, not the car. Please give the car's year and describe what happens when it is switched on: whether the fault is constant or appears after some time, and whether it concerns the picture, sound, drive or a map update that stopped before the end. Based on the description and photos, we provide an approximate quote. We confirm the exact cost after checking the unit, and we only start work after your approval.
Frequently asked questions and answers
Repair of Mercedes-Benz E-Class Coupé C207 radios, navigation and amplifiers: enquiry, module shipping and quote.
Do I need to know who made the Comand in my Mercedes?
No. Comand units in this series came from different factories and you do not need to identify the manufacturer yourself. Send photos of the front and the sticker with the part number, and we will ask about any missing details.
Does the Comand keep resetting to the logo. Do you accept such units?
Yes. Repeatedly switching off and back on, with the logo on the screen, is one of the faults we deal with. Describe how long this has been happening and whether the problem is constant, and we will prepare an approximate quote.
What should I do if the Comand has been flooded or damp?
Please mention this in the enquiry, as corrosion inside such a unit progresses quickly. Once we receive the removed module, we check its condition and confirm the repair cost for your approval.
Do you repair a Comand that does not read discs or memory cards?
Yes, we deal with drives that do not recognise discs, eject them on their own or jam a disc in the mechanism, as well as damaged card slots. We confirm the scope of work after checking the removed module.
Do you have to come to the workshop with the Mercedes-Benz E-Class Coupé C207 model?
No. You send only the removed module by courier, and we check the unit that is delivered, not the car. You arrange removal and refitting with a workshop locally.
