Same as on a W211 ECE COMAND But with the last 2 updates they took out what you all like to see.

and that method is??

May not have as many features (i didn't know to begin with so nothing lost there) but I still may find something useful.

Mackhack

There are different methods since there are different versions out.

Hi Hubi,

In my system I also dont see the euro option, only US. So how did you downgrade your system? I checked my system in Engmode and I see my software was updated sometime March 04. I wanted to downgrade just like what you did to get the Euro model option. you mentioned your software now is 15/03? version 5.182? Do I need a firmware flash update? how to do that? Please help!

Mackhack

Yes you would need an older firmware to downgrade. But since your COMAND is a US COMAND and not a ECE COMAND your hardware doesn't have the Omega DVD playback processor chip on the board. Worthless to downgrade and hoping you can watch DVDs.

Thanks MackHack, is there a way to verify the dvd unit? can I see the dvd unit spec in the Eng mode? Should it say "Omega" there?

I'm just making sure that the previous owner didn't just upgrade the firmware and made the ECE option disappear. thanks again!

Mackhack

Omega is a chip not a piece of hardware. ECE firmware won't install on US hardware and vice versa.

Here are the steps I found to make my build date 4/04 Command 50 Head Unit (HU)
Display the AMG Logo upon Start Up

Turn Car ON
Press Audio
Choose Radio
Press MAP
Press 5 and immediately 3 and 7-
You Press them All almost simultaneously but the 5 a hair quicker
HOLD Until the MENU Displays
Then Choose "AMG" w211 US
Click -Back
Shut off the car
Get out
Arm the car (lock)
go inside relax for 5 min don't watch the clock you be patient and breathe

Come back after 5!! not 4 or 3 but Yes FIVE WHOLE minutes and it'll work.

Patience is the key here.. the 3,5,7 is the easy part


btw - this only changes the display - if you want the HU to play MP3's and DVD AUDIO
You'll need to burn some software and its just as easy as this.

PLEASE NOTE - DVD (AUDIO) NO MOVIES

If anyone has figured out how to play movies please PM and ill paypal you. Its confirmed that
my HU plays DVDS but I will note that upon inserting an Audio DVD or DVD Movie the display
reads Compact Disc CD an older nostalgic looking Logo. I read a few places in order for movies
to be played it should say DVD. I do have NAV and Im also not sure if thats where you play the DVD.
So I tried by playing a regular movie DVD in my NAV and nothing. YET (optimistic)

Anyhow any info would be fantastic -

Hi

I was playing in the EM with flash update and it worked, I put my original disc with 15/03 software and it did downgrade. As for the DVD movies, I do have US version and DVD in the head unit. I was able to watch movies but then upgraded to 46/06 and couldn't change to ECE, only US where instead VIDEO we have SAT...then I did downgrade (described above) and got 15/03 - all EURO settings, but lost the single cd - it spins the cd but doesn't read... and from that time I am unable to find the solution to get this single cd working...

take care

Mackhack

If you ever need a new board because you bricked yours let me know , I have some new ones sitting around in a box! I also got a bunch of new DVD/CD ROM drives!!! They just arrived from Germany!!!

samo1

Which software should I burn DVD, to play DVD AUDIO?

I've tried it with NERO but had no luck.

Mackhack

samo1, if you don't have a DVD/CD-ROM drive in your COMAND it won't read DVDs. Yes Nero is a good choice, DVD-R are the better DVDs.

PM me your email address for the download link to play DVD (audio) and MP3 from
your Command 50 HU

Mike Duncan

Hi all
Can anyone confirm that any of these units can play MP4 movies off a memory stick at all?
Thanks everyone

Mackhack

No. Only regular DVDs (burned and/or original) can be played back with NTG1 COMAND units. NTG1 doesn't have a USB or memory card reader.

NTG2.5 has a memory card reader built-in.

I want to thank menzer for the attachments. It did work out for me i have a W211 2004 E270 CDI with original comand 15/04 that i acceded to Eng mode and hidden menus easily before i (dumbly) upgraded to 30/06 from HERE . I have read many threads world wide saying that downgrade would brick the comand or couldn't be possible to do at all. WRONG!!!! This thread was the last one i read and i just needed the 15/04 to try the damn downgrade (thanks menzer again). I DID the downgrade and every thing went smoothly till the end, one try only and VOILÁ i have Eng mode and hidden menus back again; no more video image stop when car in movement ; still can play mp3 from up and cdc cases; dvd case "eats" every dvd i stuck in no region code ****. hope this can help whoever needs. So: DOWNGRADE CAN BE DONE!

Mackhack

It's not wrong, you were just lucky. I replaced a bunch of boards from COMANDs that did get bricked because the firmware downgrade process didn't go through. And we all know there is nothing you can do but putting in the CD, the rest is in god's hand so to speak. I still do not recommend to downgrade COMAND firmware. Not to forget, you get all software bugs back from 15/04 and lose ETA display capability, mp3 (ID3 tag support).

pedroenf

Maybe i'm just lucky. I agree. But as far as i concern the recording process of the CD it's also important. Everybody knows that a bad recording can damage any update process. So, i recorded the firmware into a CD-R 700MB 52x MULTI SPEED from mitsai at 10x speed with Nero Burning ROM 12 trial version in a laptop PC.

About the bugs, i don't really care about them. Music is to listen and ETA is dispensable

Mackhack

Agreed!

I assumed by now someone would know the code for secret manu

romanap25

Any news on that hidden many code yet? Thanks

boardboy330

There are directions a few posts above yours. Choose MAP and press 5 then 3/7 with the 5 only being a hair quicker. Hold til the menu comes up. I just did it.

romanap25

I'm on about the code for unlocking the hidden menu in the engineering mode that lets you access the settings for watching DVD while driving

boardboy330

Engineering mode was posted a few pages back...

romanap25

I can get into engineers mode but I can access the hidden menu
