Teclink Optical Fiber Decoder Box for Car Stereo Mercedes ML W164 GL X164 E-Class (2008-2009) SLK (2008-2011) CLK-Class Porsche Cayenne: MOPC-1

This product worked PERFECTLY and worked where 3 other boxes FAILED to operate in an R230 Mercedes Benz 2009 SL63 with Harman-Kardon stereo/speaker system and a TOTALLY AWESOME Dudu7 12gb 9.5" 512gb storage head unit. Huuuuge upgrade for my 2009 SL63! Highly recommended.

I've bought it. I've opened the box. Soldering quality seems a little (but not much) better than me in my garage. But it works, and works well. Compared to a blue adapter box from another vendor, this gives much cleaner and crispier sound. In fact, the sound with an aftermarket system is now just as good as from a factory Porsche head unit. This adapter is pricey, yes, but worth it.

Works correctly for a 2003 W211. My car had the MB "Audio 50" head and has the Harmon Kardon system. This unit made updating from the Audio 50 head to a modern Carplay compatible unit a breeze. This unit allows the original trunk mounted HK amplifier to be used via the fiber optic connection in the front head console.

Garbage

Works great and easy to install, it's the only way that I know of where you can keep your stock amp and still be able to replace the old outdated radio.

The connector for the optic fiber does not fit perfectly and I had to secure it with duct tape. Apart from that, it works great in my MB CLK

Everything works as described, leaving 4 stars due to lack of instructions, which causes some headaches.

Pesimo! Lo compre y no es compatible con el modelo de Mercedes W211
