Available Options

This Fiber Optic(MOST) adapter allows you to retain the factory Mercedes-Benz MOST Harman/Kardon amplifier audio system when installing ANY aftermarket radios. In addition, the output from all speakers includes a subwoofer and premium sound quality. This makes for a nice clean, easy install.
When installing this interface into your Mercedes-Benz, you must ensure that the fiber optic signal loop is not broken. In addition, if you have other devices, including the original CD Changer, satellite radio, and telephone module, they must consistently stay connected to the fiber optic signal loop.
To identify if you have a fiber optics MOST factory amplified audio system, you can check the vehicle in several 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. If unsure, you can call your local dealer with your vehicle's chassis number and ask them to check if the car was manufactured with an amplified audio system. If you are unsure, please send the VIN and a photo of your car's existing dashboard to 
info@sigmacarstereo.com, and we will help you check.

Frequently asked questions:
Q.  Can I return this for a refund if I do not like it?
A:  NO. We warranty the product for one year. If there are any problems with it, we will replace it with a new one for you.
Q.  Why are there only TWO RCA inputs?
A:  It only supports stereo input from your front Left and Front Right RCA audio output.
Q.   If it only uses TWO RCA audio cables, how will I get sound from all of my speakers?
A:  The MOST interface will convert the TWO RCA audio signals into a fiber optic signal your factory amplifier can understand. Your Harman Kardon/BOSE amplifier will distribute sound to your speakers, including your subwoofer.
Q.  Can I control fade and balance after this is installed?
A:  You can control only LEFT RIGHT balance since it only uses those two RCA audio cables. No fading from Front to back.
Q.  Does this support steering wheel button controls?
A:  This does not add or remove the steering wheel button control. It only has one function: to convert RCA audio into a fiber optic signal the factory amplifier can understand.
