Mercedes ML R Series, Porsche Cayenne Car Stereo Optical Fiber Decoder

The Mercedes ML R Series, Porsche Cayenne Car Stereo Optical Fiber Decoder is a plug-and-play module designed to preserve your vehicle’s premium audio experience while upgrading the infotainment system. By decoding the optical fiber signal, it keeps your original Bose or Harman Kardon amplifier intact, so you don’t sacrifice sound quality as you upgrade your head unit.

This optical fiber decoder is tuned for a wide range of luxury models, including Mercedes-Benz ML (2005-2011), GL (2005-2011), R (2005-2011), E (2009-2012), CLS (2009-2012), and SLK (2009-2012); Porsche 911 (2005-2012), Boxster (2005-2012), and Cayman (2004-2012); as well as compatible BMW E9X, E7X, F0X and Audi 2G HOST/3G HOST systems. The decoder ensures your factory amplifier remains powered and your soundstage remains coherent after an aftermarket head unit is installed.

Key advantages include no need to route long cables from the front to the trunk—your car’s wiring can remain in place. The device connects easily at the front, reducing installation time and costs. It’s a true plug-and-play solution for a cleaner, faster upgrade without sacrificing audio performance.
