Optical Fiber Decoder Box For Mercedes BMW Audi Porsche MOST25

Product View
Add an optical audio interface to a compatible vehicle stereo installation with this MOST25 fiber decoder box. It is designed for selected vehicles using a factory optical fibre audio connection and can retain the operation of suitable Bose or Harman Kardon audio equipment when the correct vehicle and connector arrangement are used. Please compare the vehicle fibre plug and radio connections carefully before ordering, as installation differs between models and the two available versions are not interchangeable.

The box operates from a 12 V vehicle supply and has a compact 7.4 x 5.5 x 2.5 cm housing. Its construction combines gold-plated connections, copper wire and a plastic enclosure. The model reference is XYH-LZ-MOST25-01, with the pictured MOST25-01 and MOST25-02 connection options covering different vehicle applications. This is a wiring interface for compatible head-unit installations, not a universal adapter for every car with a factory stereo.

Compatibility shown includes selected Mercedes vehicles, BMW E9X and E7X, Audi 2G and 3G systems, Porsche Cayenne, 911 and Boxster, plus New Touareg applications. MOST25-01 is shown for Mercedes ML 2005-2011, GL 2005-2013, R 2005-2018, CLS 2009-2012, S W221 2005-2012 and SLK 2009-2012, as well as the BMW, Audi, Porsche and Touareg applications listed. MOST25-02 is shown for Mercedes CLS 2005-2008, E 2003-2008, S 2004-2006, SLK 2005-2008 and CL 2004-2006.

Installation is carried out at the stereo connection point:
- Remove the black plug from the decoder and take off the protective cover
- Connect the vehicle fibre optic interface to the black plug and refit it to the box
- Connect the B+, GND and audio leads to the car stereo
- Check the connector style and selected version against the vehicle before fitting
