C to C1 and C2 connector Adapter

I have seen that adapter tossed around in some threads on this site, but I have been unsuccessful in finding where I can purchase this connector?

Regards and thanks

If you have the entire harness, then I do have that already.
Thanks

You will have two blue wires and one brown wire with a connector that need to go to the passenger side.
Where are you located?

.Are they:
A034 545 7528 - C1 Connector Block
A000 545 4230 - C2 Connector Shell
A001 545 5526 - C2 Connector Block
These are numbers I received for the C1 and C2 connectors
The one that is missing is the one for the male C connector. I did not fget a good number for that part. The number I got was
A016 545 3626, but my parts source indicated that was an invalid number.
BTW, do you wanna part with that cable?
update; i took everything apart and reinstalled my original radio and everythig wokreed, except that, now my radio does not turn off when the key is removed like it did previously, but I am wondering if that is a configuration setting that got blown away when I removed the ground cable?. Once I determined that all wwas pretty much okay, I reinstalled the COMAND system and powered up. The result, the COMAND system now sees the CD changer
, but it does not turn off when the key is removed
. I know I need a trip to the dealer to get the instrument cluster and sterring wheel to communicate with the COMAND system as the ECS?, does not know its there. i am waiting to finish hooking up the Factory Sirius Radio which I started last weekend just after the completion of the first install of the COMAND system. i will need to comlete the front trunk fiber hook up and the proceed to the rear passenger area to do the final hookup. I will not hook up power to the receiver until I am at the shop and ready to have the dealer configure it with Star Diagnose - at $100+ bucks per hour!
I think i will go take some lunch to the night shift there and see if they will at least peek
at it for meThanks

Keep us posted.
Keep us posted.
hmmm, I will recheck the C2 connector. I do think it is really in there, as it does take a little force to get it out. It won't go in if you put it in the wrong way.
You mention the locking clip, are you speaking of the locking clip on the car's CAN B connector block? I removed that everytime I inserted the two pin connector. Reversing the connector does not allow insertion into the block, but I will do is inspect the block and see if the instertion of the connector is doing anything to the pins in the connector block. It is strange the CD suddenly started working? That does mean the CAN Bus is communicating at some level with the COMAND unit right? I just cannot figure why the Steering wheel buttons and the ignition have no effect on the COMAND unit?
I think the first thing I will do is move the CAN B connector over to another port on the Connector block and see what the effect that has on the COMAND unit as the CD came on after the move one slot to the left of the other connectors.
Second thing will be to check the state of the C2 connectors, if a pin or two are bent, that could be the cause.
One additional Question - what is a sign that the D2B wakeup is not working properly?

Everytime I pull it apart and reinstall, something positive happens?

I pulled it apart again, examined all the connectors, installed C2 before C1 this time and reinserted the CAN B plug again. Well the steering wheel can now see everything. The COMAND unit shuts off shortly after the key is removed. Now all that has to happen tomorrow is for it not to shutoff 30 minutes into my commute after asking me to turn on the ignition or it will shut off in 3 minutes, while i am going down the road at over 65 mph!

So as of tonight, the install looks good. It was driving me
I plan ito install the MBZ retrofit GPS antenna behind the speedo when it shows up. Same day I will install the Sirius antenna - dunno if I will go ahead and install it in the trunk lid or try it out on the deck beneath the rear window. either way it will work, unless I move more north!
