Compatible Fiber-Optic Interface:

When installing this interface into your Mercedes-Benz car, you must make sure that the Fiber-Optic signal loop is not broken. If you have other devices which can include original CD Changer, satellite radio, and telephone module, they must stay connected so the fiber optic signal loop is consistent.

To identify if you have a D2B Fiber-Optic factory-amplified audio system, you can check the vehicle check the vehicle in the following ways:
- Some vehicles will have clear markings on the speaker grills indicating the presence of an upgraded audio system.
- You can also check with the original order notes/invoice from when the car was purchased from the factory, the upgraded sound system with an amplifier would show on the options list.
- You can also check for details in the below pictures, or contact us to send related pictures to check before buy to avoid mistake.
