Thanks!
I did tap into the wires in my CANBUS. I didnt want to solder extra wires to reach the bus bar under the driver's side just to tap into whats there. Like you stated, there is no place to "plug into" unless you make your own connector. I went the simpler route, for myself, and just tapped (I used Scotchlok connector) into the CANBUS from my climate control. I looked at your MY and it looks like your climate control is above the head unit so I am not familiar on whether or not it has the wires accessible for it there. The previous MY for the CL had the climate control underneath the Headunit (from what I see in pictures). If you see a twisted pair of brown and brown/red from the climate control area, that should be the CANBUS. I don't want to steer you wrong since I know the S55 and the CL55 have a different dash setup. (I am assuming CL55 by your info on the side). Wish I could help more.
For this threads purpose, to clarify my earlier posts, my fiber optics decoder box was faulty. Once I replaced that, everything worked fine. Well, I still need to find connectors and wires to run to the trunk for antenna and gps but, not trying to get into that as I don't know if I am keeping this Fleabay Chinese headunit.

Hello I am upgrading 2006 S500 system to new xtrons head unit. I connected everything so far minus the can bus connections. Someone mentioned I could tap in the ac unit brwn brwn/red wires? Tried it but got nothing no illumimation lights on the unit no steering wheel vol control. Also my unit has a can bus decoder with green green/blk wires coming out of it.
Also I need help locating the radio antenna wire in trunk I see s wire which says antenna that is connected to another wire that says lct. Is this the correct wire? If so will I need a adapter to fit this end from female ext antenna cable?

decoder box
Its probably a bad fiber optic decoder box. I personally had that happen to me. EVERYTHING worked but I had no sound. I thought it was bad connection somewhere but I had a bad decoder box and ended up buying a new one that fixed my problem. I cant say hundred percent say that is your issue but if I would have to guess than I would say that would be it.

I guess I’ll just order the long cable, it is so frustrating, I give up :/

I ordered another optical box the seller this time sent me a box without canbus wires, he said this box is newer, I tried it no sound, but anyway how this new box suppose to work if it doesn’t have canbus wires?? I know canbus wires are important to wake-up the amplifier

I just looked at the decoder box and there aren't any canbus wire attachment. It just has a power and ground with an RCA input. The Canbus wires most likely come from the head unit itself. I'd have to pull mine out of the box to look what wires were included in the head unit.
I figured that if it was the decoder, even though AVIN doesn't refund they will exchange if defective. So, I went ahead and purchased one from them and it worked no problem.

Once you get it together and working you'll look back and think...that was actually pretty simple but what a pain in the a**
Good luck

Hi,
W463 2002, bought Isudar Android Headunit but the steering wheel control doesn't work.
The radio turns ON itself, there is a signal for the backup camera when in Reverse but NO steeering control.
I dont know if the CAN is correct or maybe the CANBOX wrongly set? Any ideas how to connect to the steering Canbus will be appreciated.

I have a 2005 S600 and am in the same boat. I ordered a new decoder, i know my decoder DID work at one time as i tested it in place of the CD changer. I ordered a new one and will try it.
Thanks to all that have posted in this thread it made life SO much easier.

I"m having the same issue of no audio. I have a feeling the canbus decoder with my headunit isnt telling the system where the audio input is coming from. all the other canbus functions work though. i tried pulling the cd changer out of the fiber loop too. i'll try relocating the fiber decoder to where the changer was and see if that works.

i've been round and round in trying to get the Audio Gateway and amp to turn on with no success, at this point i assume it has something to do with my CAN BUS interface not knowing how to "wake things up". thank you all that have posted to this thread.

I will be installing a universal Android headunit that used to be in my Nissan. I hope I can get everything working including the steering wheel controls as I don't have a canbus decoder (but my headunit harness has CANBUS cables "Key 1" and "Key 2").

Hi Russ
I'm looking at this on my phone. I don't see the PDF. Can you help.
I tried wiring an aftermarket head unit with a fiber optic decoder box. Nothing worked and so I'm in the process of returning everything.

Thanks got it
Hi DIY
i did have those instructions. Have you done the install?
do you have A MOST audio?
I would be able to help you the best I can as I've gone through this and hot stuck quite a bit.
Does your OEM head unit work or did it die?
Mine is dead. So I cannot reset the clock! I need to either get another or figure out the aftermarket route.
Thanks

I haven't yet installed my aftermarket AHU. I am making some mods to the dash first. Will post pictures once I am done. My factory head unit is a MOST and it works except for the CD eject function. What did you end up doing?

Hi,
So as I mentioned. I returned everything and have basically ordered a used Command unit from Ebay. I'm waiting for that to arrive. My main issue was that the command unit itself died.
I have also ordered a Y split MOST fiber optic connector:
https://www.ebay.com/itm/MOST-Fibre-...72.m2749.l2649
I'm hoping to receive it and then start afresh with this.
Hopefully you will be ahead of me and we'll know what happens.
I want to make sure that your unit has RED "End" and GREEN "Send" buttons to make sure we share the same audio system.
Can you tell me that?
Thanks
Kannan

As I had mentioned, I am installing a universal android head unit.
I tried keeping factory amp and all components by buying the $100 fiberoptic module for sound.
Given that the module only uses the two front speaker inputs, the sound quality was poor for me since I am an audiophile.
I also started getting more battery drain and had to replace my 6 month old car battery.
Therefore, I returned the module and ripped out all that old technology from the trunk. I have run my own speaker wires to the trunk for factory speakers.
I have also installed a 2 Channel 1200 Watt Boss Amp that is powering the factory subs. It sounds great! I tried PAC steering wheel control module, but couldn't get it to work.
So I am returning that too. I have this (https://www.ebay.com/i/323490505036?...AaAp75EALw_wcB)
that I bought some time back for my previous car for cheaper and will use it instead (already tested and works).
I have installed wireless chaging in front ashtray and also USB charging in armrest. Will be posting a video on Youtube and linking it here soon.

Hi Arnoldo,
Did you get your aftermarket head unit installed yet?
If so:
1.) How and where did you connect into the Mercedes CANBUS system wiring such that your steering wheel controls function?
2.) How did you use the Blue/Black-stripe wire with your installation?
If you can supply pictures, that would be GREAT!
Thanks,
Russ
