W220 Comand 2.5 rear connection pins confusion.
I am doing an Audio 10 to Comand 2.5 conversion. The connector from the Audio 10 fits the highlighted spot in the Comand 2.5, but it is wired differently, so I need to know what the pins on the Comand 2.5 unit are for.
I found this page https://pinoutguide.com/Car-Stereo-M...T_pinout.shtml , but the drawing info does not match the written info, so I just get more confused by that one.
Anyone know for sure what these 8 pins are for?

here in the last post (sent by myself) you can find the correct pin out, for the Comand 2.5. KL30 is permanent 12V + (battery), KL 31 = ground.
So the white and green CAN wires from the car doesn't go in the A connector which I thought. Do I have to get hold of a C2 connector type male and connect the CAN wires to C17 and C18 for the steering wheel buttons to work?
I don't know exactly the wiring of the audio 10 in comparison to the Comand 2.5. But, as I understood, you are trying to replace the audio10 by a Command 2.5, right? The connections required to run the Command 2.5 are, D2B fiber Optic, Plug A for the power supply, Plug B for the speakers, 3 Antennas (GPS, Radio and ZF (I think its called diversity??) Plug E to connect the navigation with the radio component and Plug C2 for the CAN Bus and connection of the speed signal and the Plug E. All plugs are FEMALE, the Comand side are all MALE. MB has the inserts with wires for the plug and sockets available, which can be inserted into the plug (female) and socket (male). See attached picture. Its in german but I guess self explaining. The first item is the wire with the inserts, the second is the plug C2 and the third is the plug housing. To run the Comand 2.5 the CAN bus C2/17 and C2/18 are essential.

Ok - I wrote C2 MALE connector because I thought the term was regardig the connector itself, not the pins/receivers. But if it is like that, I understand, the plugs from car are female and the Comand pins are male, because Comand has the pins. Got it

Ok, so I do need all 3 of those parts? They are all for the C2 so the one in the middle goes inside the housing?
These are the connectors from the car. White and Green are CAN, the blue/black I am not sure of. Neither sure of any of the Brown, Gray, Light Gray/Black on the other 3 wire connector.
Anyway - I don't bother with navigation or CD changer to work, the only thing I want working is Radio, steering wheel controls, and of course display and backlight, and auto on/off.
Thanks again for your help. Appreciated.
Yoy don't have the part number for the C1 Aux connector and wires by any chance? That would be nice to have, but not critical for me.
Plug E goes in the lowest 26 pin connection on the Comand unit or what? It would have been nice to see a Comand 2.5 with all the plugs connected just to get a visual view of how it's supposed to be.

This is what I have for the Audio 10: https://pinoutguide.com/Car-Stereo-M...D_pinout.shtml
So radio works, screen works, but - auto on/off does not work, i can turn on and off manually but it is not controlled by ignition.
Any ideas? Cant seem to see what pin should get 12v ignition input on the Comand unit? There are 2x Kl.30 (12V permanent) but no 12V ignition?
There is one more thing I wonder if I need. I see there is a wire called K-leitung coming from original car harness going into original Audio 10. This I have not connected to anything as of now, but I see on the C connector on the Comand, the same K-leitung input. What is it, and should I connect it?
Btw, I see I posted this in the wrong thread. It was supposed to go into this thread: https://mbworld.org/forums/s-class-w...confusion.html. Sorry for that.
Green wire = can-h and White wire = can-l, right?
