Secret menu in the 05's COMAND unit.
but the problem is the single CD slot doesn't recognize the CD - its trying to read but nothing is coming up on the screen and it said that there is no DVD for example...
The questions is how to repair it thorugh the Engineering menu....

Can I flash everything agains through the eng menu? maybe then the single slot will work.....
How did you downgrade your firmware?
From another DVD movie thread I just bumped...
Ok, so I usually skip over all of the DVD movie threads, as I've always barked that US COMANDs lack the hardware to play DVDs, save for the rare 2003s and the early 2004s that got DVD ROMs, in place of CD ROMs.
My 2004 E500 will not read DVDs at all, even MP3s on DVD, but it will play MP3s on a CD, after I updated the firmware on the COMAND. Great, super.
But, my 2005 SL600 does have a DVD ROM, and I've always been able to play MP3s on a DVD. Great, super.
But after reading this thread and a few others that have been bumped recently, I decided to pop in a movie to see what happened. I wasn't expecting anything but an error, but I'll be damned if it didn't load and start playing. Not great, not super. Ahhhh, why you ask? Because it activates the driver distraction feature and blacks out the screen, even though I was parked. But at least I was able to prove the theory that some of these cars do, in fact, possess the ability to read the movie.
None of the backdoor codes get me into the engineering menu. I'm guessing since I updated my map disc with the latest and greatest, I've screwed myself.
Any ideas?
Here's a video. Don't laugh at the beginning. A big *** bug, the size of a small rodent, landed on my hand.

Yeah, the instant I put that new map DVD in, I screwed myself.
Will the SDS need to have Developer Mode enabled to activate VIM?
Yes sir, it's in the back. But I distinctly remember it updating the COMAND when I inserted the map. I found it odd too. It went through the entire update and reboot, just as if I were to use the firmware update disk.
However, I used the firmware update disk on my E500, in the COMAND drive, and updated that car that way.

Nav drive firmware update has NOTHING to do with COMAND firmware update. I'm battling this issue now for 2 weeks in different forums. Not sure why people just don't comprehend that those 2 units are completely separate and use 2 completely separate updates (not saying people are dumb, just don't understand I guess).

I didn't go digging into any of them, but you might recognize them.

Oh, I certainly understand that they're mutually exclusive. However, I can also say with zero degree of uncertainty, that when I popped that map disk in the NAV drive in the trunk, my COMAND stated that it was doing a firmware update.

What you saw is the update process of your Nav Drive...
not of your COMANDPS: even my dog jumped when I wrote that! haha
Ok, so hold on.
I just pulled the files off of my COMAND firmware update disk, and I don't see any matching files. So, I'm willing to concede that my COMAND's firmware didn't get updated by the map disk, but something did.
I think we both agree now, that the MAP disk updated my NAV drive. But thinking about it, what the hell would it need to do that for? The map drive only contains....well map info, right? It's constantly spinning that DVD back there, and reading the map data real-time, no? It doesn't download the data off the DVD and store it on an HDD. It's just reading the disk, and performing I/O as needed. What's so different about this map disk, that it needed to perform an update on my rear NAV drive?
Or am I over analyzing this? It's the engineer in me, it's what we do.

Each time you buy the latest map DVD the drive's processor has a routine to check if it needs to get updated. If yes, you will see the 2 progress bars in your COMAND showing you the update process of the nav drive's firmware. If you don't see them, it doesn't update anything.
The nav processor does more than just reading navigational data. It takes all the single voice samples and puts them together to generate a full sentence. Each number (digits) each word is one single sample on the DVD. When she whispers in your ear something like "Please use next exit and make an immediate right turn" then your processor in the trunk took 10 works put them together and voila you got the woman talking to you.
Sorry, my sarcasm came out a lil bit but makes sense what I'm trying to explain, right?
