Batianda Optic Fiber Decoder 2 in 1 accessory

SKU CH-ZJ1T-6RAVV

A fiber-optic decoder that retains the original amplifier and Bose or Harman Kardon systems when fitting an aftermarket head unit to compatible Mercedes-Benz, Porsche, BMW, Audi and VW models

  • Keeps factory Bose or Harman Kardon sound active
  • Works with Mercedes ML, GL, R, S, CLS, SLK models
  • Compatible with Porsche 911, Boxster, Cayman vehicles
  • Supports BMW E9X, E7X, F0X and Audi 2G/3G hosts
  • Front-only wiring avoids long cable runs to trunk

Vehicle Compatibility

This fibre-optic decoder works with Mercedes-Benz ML (2005-2011), GL (2005-2013), R-Class (2005-2018), S W221 (2005-2012), CLS (2009-2012) and SLK (2009-2012). It also supports Porsche 911 (2004-2015), Boxster (2004-2012), Cayman (2004-2016), BMW E9X, E7X and F0X chassis, Audi 2G and 3G HOST systems, plus VW Touareg (2011-2017).

Factory Amplifier Retention

The unit decodes Bose or Harman Kardon signals via an optical interface so the original amplifier remains active after an aftermarket head unit is fitted. Vehicles equipped with those premium audio systems require the additional optical fibre box for full integration. Standard audio systems without fibre amplification are not supported by this adapter.

Installation Scope

A grey plug on the head unit is removed to accept the fibre wires, then the connector links to the CAN-bus box at the front of the vehicle. All wiring stays in the dashboard area, eliminating the need to run long cables to the rear. Buyers whose cars lack a front-accessible CAN-bus connection or who prefer a fully wireless integration will need a different solution.

Questions about this item

Will this decoder work with the existing fibre-optic amplifier in my 2011 Mercedes-Benz ML?

Yes, the decoder is listed for ML models from 2005 to 2011 and keeps the original fibre-optic amplifier active when you fit a new head unit.

How can I verify the decoder is functioning after I connect it to the CAN-bus box?

The factory speaker system should play audio from the new head unit immediately; if sound comes through all channels the fibre link and CAN-bus integration are working.

What comes in the box and do I need a separate fibre box for a Harman Kardon system?

The package contains the decoder unit; an additional optical fibre box must be purchased separately if the vehicle has a Harman Kardon or Bose amplifier.
