Review: Worked perfectly in a 2009 SL63 R230 Mercedes-Benz convertible - 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.
Review: It's very, very good - 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.

### ⭐⭐⭐⭐⭐ Worked perfectly in a 2009 SL63 R230 Mercedes-Benz convertible
*by J***E on October 21, 2025*

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.

### ⭐⭐⭐⭐⭐ It's very, very good
*by R***N on January 27, 2024*

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.

### ⭐⭐⭐⭐⭐ Easy simple install
*by L***E on November 4, 2023*

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.
