Frequently asked questions and answers
Repair of Mercedes-Benz SLC R172 radio, navigation and amplifiers: enquiry, module shipping and quote.
Do you need the system name for a request for the Mercedes-Benz SLC R172?
No. Photos of the panel and the rating label, plus the car’s year, are enough. We will only ask for the part number if it turns out to be needed to identify the unit.
Why do you need a photo of the sticker?
The sticker with the part number allows us to identify whether the unit is factory fitted. This matters, because we do not repair replacements fitted instead of the original radio.
Does the repair start immediately after the module is delivered?
No. First we test the unit on the bench and give you the exact price. We only proceed with the repair if you approve that price.
Will you determine whether the cause lies in the car rather than the radio?
We test the removed module only, without the car. The power supply and wiring in the car remain outside our assessment, and such checks should be carried out by a local workshop.
Can I deliver the module myself instead of posting it?
Yes, the unit can be delivered in person by prior arrangement. Another option is to send the removed module by courier, without bringing the car.
For the Mercedes-Benz SLC R172, we repair the factory radio, navigation system and amplifier. We start every enquiry by finding out which module you have in the car and exactly what is happening with it.
Do I need to know which radio I have in the car?
No. You do not need to give the name of the system or its version. Take a photo of the panel and the rating label, if you can access it. If we need the part number, we will ask for it in our reply. That same label shows whether the unit is factory-fitted – we do not repair Android replacements.
What should I write about the fault?
Three details help us with the initial assessment:
- what does not work: picture, sound or response to the buttons,
- when it shows up: straight after switching on or after some time,
- whether the unit has been repaired before or is asking for a code.
Also the car's year. With that description and the photos, we prepare an indicative quote before the unit reaches us. If there is no sound and it is not clear whether the radio or the amplifier has failed, we agree in advance which items are needed before dismantling.
What does the inspection involve?
Only the removed module is sent to the workshop. We test it on the bench, without the car, so we do not assess the wiring or power supply in the vehicle. After testing, we give the exact price. We only begin the repair if you accept it. The decision is always yours.
