Frequently asked questions and answers

Repair of radio, navigation and amplifiers Mercedes-Benz C-Class S204: request, module shipping and quote.

Do you repair the factory radio, navigation and amplifier in the Mercedes-Benz C-Class S204?

Yes, we repair factory radio, navigation and amplifier modules from the Mercedes-Benz C-Class S204; we do not service Android replacements. We check the removed module and accept shipments from across Poland.

Is it worth repairing a module in the Mercedes-Benz C-Class S204 instead of replacing it?

Whether repair of the Mercedes-Benz C-Class S204 is worthwhile depends on the type of fault and the condition of the supplied module; before inspection, we do not decide whether replacement would be better. You will receive an approximate quote after photos and a final one after inspection.

How is a repair quote prepared for the Mercedes-Benz C-Class S204?

An initial quote for the Mercedes-Benz C-Class S204 is prepared from photos of the front, the label and a description of the symptoms before sending. After inspecting the delivered module, we will confirm the scope of work and the price before the repair begins.

Do I need to bring the whole Mercedes-Benz C-Class S204, or is it enough to send the module?

You do not need to bring the car – send us the removed Mercedes-Benz C-Class S204 module or deliver it in person by arrangement. When packing, protect the screen and connectors, use a rigid box, fill the package and send any extra parts separately.

What should I prepare before submitting a Mercedes-Benz C-Class S204 module?

When submitting a request, provide the make, model and year of the Mercedes-Benz C-Class S204, describe the symptoms and attach photos of the front and the rating label. Based on this, we will give an approximate quote before shipping and a final one after inspecting the module.

Repair of the radio, navigation and amplifier in the Mercedes-Benz C-Class S204 covers the factory Mercedes-Benz Audio 50 APS radio-navigation system (Harman Becker), used in vehicles from around model years 2007–2016.

How do you identify Audio 50 APS?

The front panel of this unit may be graphite or glossy black. Regardless of version, the Harman Becker Audio 50 APS has no SD card reader. The rating label on the right-hand side of the unit confirms it – it shows the part numbers. The unit comes with either a single CD/DVD drive or a changer.

Faults we can help with

Audio 50 APS units arrive at our workshop having stopped starting up properly:

  • they keep resetting cyclically – the menu appears, the system switches off and after a moment turns on again,
  • they do not turn on at all, neither after turning the key nor by switching on manually,
  • they freeze on the Mercedes-Benz logo,
  • they request the anti-theft lock code, although they have not been replaced.

Decision to repair

We check the removed unit first and only then define the scope of work. In your enquiry, describe which symptom occurs and whether it happens every time. Attach a photo of the front and the label, and give the make, model and year of the car. On this basis we prepare an indicative quote; we confirm the exact price after inspection, and carry out the repair after your approval. We do not repair Android replacements fitted instead of factory units.
