Secret menu in the 05's COMAND unit.
I went through HELL looking for solutions to play my huge collection of mp3's before I received my CDI. In the end, everything was built in.
Just to clear the air once and for all, the North American standard COMAND units in the 2005's will PLAY mp3's burned on cd's AND DVD's. Period.
Before that, I don't know.
As far as playing VIDEO DVD's, so far, no one has found out for sure if the 2005's standard COMAND units can play videos.

It seems the 2005's are a Voyage Of Discovery. NOBODY at my dealership knows much about the 2005 COMAND capabilities yet.
We should NOT assume that the DVD head unit can play video. It is highly likely that there is a hardware decoder and it may be lacking in the North American versions. The only way we will know for sure if we try it. So far, Shrek comes out as "cd error".

On a side note, I noticed a Developer mode as well. I wonder what can be done through that mode?
The philips drive has a DVD decoder chip on it (SAA7816HL). And a ribbon connectors is used to connect it to the control unit.
From the picture it looks like the same connector is used to connect the toshiba drive to the control unit (if that is the case, it means that toshiba chip should be a DVD decoder chip). I can't read the toshiba p/n off Steve's website. So if anyone can give me that information, I can look into this further. I believe that if we can locate a SAA7816HL based DVD drive, it should be a direct swap of drives into US command.
It's not the laser that differentiate the drive, it's the decoder chip that comes with the drive. I am about to trade my Command for a euro one. So I am not going to mess around with my command. But I think there is a cheap solution to get this to work. However, we are still missing connectors for the video, which is a must for me.
So if anyone want to volunteer their 2004 US command and let me know the toshiba chip p/n on it. I can dig into this further.
ANYDVD- disables region code
clonedvd- burn backup copy of your dvd.
information is only intened to make legal backup copy only.
I'm still shaking my head at MBUSA's logic.
BUT...all of this is of NO USE to 95% of you people with a US comand as the US comand in NO WAY is able to play DVDs unless you are blessed with one of the very first US cars with a factory equipped comand. The US comand is NOT able to play DVDs (believe me, I have sacrificed two of those in order to get it worked out).
The US spec W211 comand can be forced to recognise DVDs (by doing a lot more then just the 357 trick) but the maximum DVD experience out of a US spec comand is a set of horizontal lines on the screen and that is it...the US spec comand is not able to decode DVDs NO MATTER WHAT REGION the DVD is (which is a complete different setting then the ECE versus US setting).
On euro comands with the latest software (MP3 compatible) the 357 trick no longer works...I don't know how that is on US spec comands as I have not been able to find software updates for those yet...
The 357 trick only works when the HU gets switched off, the car gets switched off completely as well and one waits for at least 3 minutes before the car gets started again...when first switching on the comand it will reboot and the display will stay black...if it powers up right away, the 357 trick wasn't succesfull.
On the older US spec comand that do have DVD playback acapbillity, I only could get the DVD to play while the car was not in motion...and could not get it to play DVD while the car was in motion. Whenever the HU was switched off, the DVD would start at scratch again when switched on...not at the spot where it stopped.
These older US spec comands with DVD playback are only used for a very short while before the real US spec comands were installed...so don't hold up your hopes too high of finding such a comand in your US spec car.

The euro comand in scorchies E55 comes up with SAT in US mode and comes up with TV, AV1, AV2 and DVD in ECE mode when hitting the video (SAT) button
greetingz,
You should differentiate between DVD-video and DVD-audio. Some people are getting confused between the two. Some people are assuming if it can play DVD mp3’s then it should also play DVD video’s. Which is NOT true.
Just so some of you are not confused.....
DVD stands for Digital Versatile OR Video Disc. It’s a higher density data storage medium that can store anything digitally. The problems arise in decoding the stream of information that is read by the laser. It is not a stretch nor surprising that MB upgraded to a DVD reading unit since that is becoming the standard. Nor is it surprising that one can play mp3’s on it.
However……
The problem arises when you need to decode that digital stream into video. You can either do it through software and a fairly powerful computer or dedicated decoding chips. The easiest way is the decoding chip because it does not put as much “overhead” work on the computer itself. The chips themselves are fairly inexpensive but with the car manufacturers trying to save everything they can, they WILL remove them if it saves them a few dollars.
Anyway……
I am not saying anything new here. This discussion has already taken place in a few threads.

Knowing why the decision was made won't do anything for my pocket or love life. It just irks me when an illogical deduction is used to pontificate an answer to even a trivial question, then repeated until it becomes an urban legend.
- Because it is illegal in the US
- Because MBUSA suits are losing it
- Because they wanted to ***** off their US customers
Jeopardy question: Why did MBUSA omit the DVD decoder chip in the US COMAND units?
Take your pick.

So......
One can only use what is logical, reasonalbe and what is common practice in the automotive industry. We could debate the point but it will not give us any real answers.
But don't worry.....
I'm planning on stealing a fellow members car and giving it open electronic heart surgery.....
