Pre-MOST (D2B) Fiber Optic to Digital Decoder for new headunit
Hi there,
Been rebuilding a 2002 C32 that had seen a few years of neglect. Am loving the vehicle and have been putting countless hours into bringing it back to life (electronics sorting, engine refresh, all the fluids, seals, body work).
My current projects are replacing the foot well climate control stepper motor and linkage, and at the same time replacing the headunit. My focus here is the headunit which is to integrate with the BOSE sound system which has the D2B fiber system, all oem BOSE speakers and amplifier, no cd-changer, teleaid, audio 30 interface. I have done enough research and going through the forums and interwebs with no success at finding a fiber decoder (Mercedes uses a proprietary signal apparently) to convert the new headunits signal to the required fiber signal and complete the ring through the amplifier.
It befuddles me that NO ONE had ever come to a solution to this, as the MOST system has dozens of options to decode the signal, however, if I am wrong, can someone please fill me in on the decoder to prevent me from having to run a new amp and cables to the rear.
Thanks and best.

I replaced my OEM Comand with a unit from Erisin and I dumped my Bose amplifier. Will always sound better with a dedicated new 6 channel amp but for now it sounds just fine with the built in amp.

Hi, i got a same question. I am planning to buy a Erisin head unit for my 2003 W220. It seems it use the D2B fiber optic. But i cant find a decoder on the whold Internet. means i have to do like u dump the Bose amplifier away？But i really want a Android head unti for carplay because the oringal one got a black spot on it. But i am worry about the sound on the Erisin unti to the speakers.
Does it really sound very different between Bose amp and Erisin built in amp? help me decide, lot of thanks!

What Erisin did you install? I just want to make sure what I purchase will fit. Also, I assume the existing optical fiber is limited to only the head unit, cd changer, and bose amp? All you did was bypass all of that and directly drive the speakers from the Erisin?

What I got at the time was Erisin ES7963C. They may have other models by now. I have removed this existing optical fiber wiring and the Bose amp and wired the speakers using Erisin LMBENZ-6M cable that I ran from the head unit to the place where the Bose amp used to be. Just in case if i decide to add an amp later on. But so far it sounds just fine as is.

I went with a new pioneer speaker system and the sound is truly great. Had to cut out some of the sheet metal to get the subwoofer in, but it is tucked up and covered in the rear.
I still don't have the steering wheel controls working and don't plan on screwing with it anymore.
Ditch the old and put a whole new system in, you won't regret it.
