Optical Fiber Decoder Most Box for Car Stereo Radio for Mercedes Benz ML/GL/R Series and for Porsche 911/boxster/Cayenne Series

I have another aftermarket head unit in a 2006 Cayenne. This adaptor restored the functionality of the steering wheel controls. Installation was quick and easy. Great functionality at a great price.

Ez install in my 2006 Porsche Boxster S.

The plug with the ground, 12 volt, and accessory has to be cut off and spliced into your radio wire harness for this to work. My car did not have that plug.The optical cable plugged in no problem. Super simple once I figured out the issue with the piece I had to cut.

Worked as mentioned

Have a GL450 with optical sound and upgraded the radio to android 11 and this worked like a charm.IMPORTANT TIP: the ACC wire should be connected to the ACC wire output radio you’re installing NOT the car’s harness - for Mercedes at least… or you’ll drain the car battery overnight. Don’t ask me how I know that lol

Stereo company unable to get any transmission to stereo with box used no power at all coming through box

Works perfectly with an aftermarket Android stereo purchased from AliExpress.

This works nearly perfectly with just the occasional time I need to power down and power back up to get it to work when there is no audio. But my issue ends up that CANBUS for the headunit is over most bus on my car. There is a third connector I suspect is for the canbus connection but it never came with a cable for it. If the seller could reach out to me and give me some support. I will gladly revise to 5/5.Thank You
