We handle Mercedes-Benz GLS X166 radio, navigation and amplifier repairs in a fixed order: first the information, then the module, and finally the decision. This applies to factory units removed from the car.
First the information
Before anything is removed, we ask for the car's make, model and year, a description of the symptoms, and a photo of the unit or panel and the rating label. You do not need to know the radio model name. On that basis, we prepare an initial, indicative quote and agree which item should be sent. This is especially important when there are sound problems and it is not clear whether the radio or the amplifier has failed.
Then the module
Only the unit itself is sent to the workshop: the radio, navigation unit or amplifier, and if the sound problem is unclear, we may ask for both modules. We test them without the car, so we do not assess the power supply or wiring in the vehicle. We accept factory modules, identified by the label with the part number. Android radio-navigation systems fitted in place of the original unit are not eligible for repair.
Finally the decision
After testing the module, we confirm the exact price. The earlier quote based on the photos and description is only indicative, so only this price is the basis for the decision. From that point, the choice is yours: we carry out the repair only if you accept it. The repaired unit is tested before being returned. Reinstallation in the GLS X166 is arranged locally, just like the earlier removal.
Frequently asked questions and answers
Mercedes-Benz GLS X166 radio, navigation and amplifier repair: enquiry, module shipment and quote.
Where do I start when submitting a repair request for a radio from a Mercedes-Benz GLS X166?
By sending us the brand, model and year of the car, a description of the symptoms, and photos of the unit and the label. On that basis, we prepare an initial quote before you remove anything.
In the Mercedes-Benz GLS X166, should I remove the radio first and then ask for a quote?
It is better the other way round. We give an initial quote based on the photos and description, and at the same time we agree which item should be sent, so dismantling can be arranged only after those details have been confirmed.
What do you check in the module from the Mercedes-Benz GLS X166 after receiving it?
We check the unit you send us, without the car. We do not assess the power supply or wiring in the vehicle, and after testing the module we confirm the exact repair price.
Can the repair of a module from the Mercedes-Benz GLS X166 start without my approval?
No. After testing the unit, we confirm the exact price and wait for your decision. We carry out the repair only if you accept it.
Who reinstalls the repaired module in the Mercedes-Benz GLS X166?
Reinstalling the unit, just like removing it, is arranged with the local workshop. The service deals only with the module itself and tests it before returning it.
