NO camera image in Reverse
The first two times this happened, I thought it was a fluke, so I reset the system (losing all my settings). Problem went away, fixed for good I thought but resurfaced today.
I was not able to see anything pulling out the garage, then 50 min later, without shutting the car off, I engaged the Reverse in a parking lot, and saw an image. I'm wondering if it could be a loose connection somewhere.

I never thought the camera was much use, but now that I can't see ANYTHING from the camera, I miss it!

Sounds like a loose camera wire to me.
It sounds software related to me since it happened after the update and it goes away, albeit briefly, after reset.
One thing I am sure of is that the update changes the order of the booting of various components. When I first got my car, the phone would pair almost immediately, but the camera took a long time to boot. I could be almost out of the garage before I got a picture. IIRC, the picture was blank, just like yours.
After my update, the camera is ready almost immediately, and the phone is ready sometime later, about 30 seconds or so.
So, it could be that your camera is not ready when you are. This might be because the camera is slow to boot, or maybe some other part of COMAND is somehow hanging or is slow. I don't really know what to suggest, other than to sometime leave the car in reverse for a while and see if the camera eventually comes on. That is why it might work after you have been driving around a while.
Of course, a loose wire is always a possibility...
I think Arrie may be right that it may be loose wire. I couldn't reproduce the problem later this afternoon and evening on the drive home. It's not often that I would want to be reverse, and it's not like I can just leave the camera engaged in Drive. I'll start maintaining a log.
ttoE550, this is very plausible. I noticed that the system when resetting when I forced it, takes quite a while to reset before all functions are available. If its not displaying because it's busy, that is disappointing. As I'm in a garage and start the car, backing up is usually one of the first things I do, as I don't want to idle the car in the garage with all those fumes.
Mercedes, if you are following this thread, put some more processing power in your cars!!
Just go back dealer and tell them of your compliant(s) and ask for another update using the latest discs.

BTW, I have had a black screen about 4-5 times over the course of 3.5 years. Only happened when backing out of garage and then not again for a long time. I think one thing that caused it a couple of times was that I was switching between radio and music register or nav and audio immediately after I put it into reverse.

I'm waiting for the day it slams me into Park and rips the Park pawl out of the transmission.
What's the old saying? ''The first thing we do, let's kill all the lawyers.'' Shakespeare, wasn't it?
Yes, if mine is running and in gear, and I shut the engine off, it goes automatically into Neutral. If I then open the car door, it goes into Park. That's great.

I don't know if anyone else has had this happen. Seems like a bug.
Dealership replaced COMMAND UNIT P/N A2129002812. On work order it says that the they found error code C264 "Communication with backup camera has a malfunction".
I hope this is the end of it.
