If your Mercedes has the fibre-optic amplifier sound system such as Harman-Kardon or BOSE, then instead of bypassing the amplifier when you change stereo you can keep it! Buy this fibre-optic decoder box and the replacement head unit will work with your amplifier sound system directly.

This adaptor is a plug-and-play adaptor required in vehicles which have an original Fibre-Optic sound system. This decoder provides high-quality audio and video levels for your in-car entertainment needs. 

To identify if you have an amplified audio system, you can check with the original invoice received when the car was purchased from the factory. Some vehicles will have clear markings on the speaker grills indicating the presence of an upgraded audio system. Or you can call your local dealer with your vehicles chassis number and ask them to check if the vehicle was manufacturer with an amplified audio system.
