How To Access Engineering Mode
Hey, do any of you know the codes for entering the COMMAND hidden menus? I have tried so many codes and it is still not working. I have a 2010 vehicle. Any help is appreciated. Thanks!

I rather think it's mostly mythology that there is an "engineering mode."
For one thing, Mercedes made in USA use Alpine units rather than the Becker units seen in many Euro-produced models and you can count on them being different.
I do know that for the Becker units, once you did one of the required firmware updates you eliminated any possibility of "engineering mode."

It isn't mythology...I've opened it myself on my C63 using end phone call, # and 1 simultaneously.
And that is how MB updated my COMAND to add RSE capability. I just don't have the code for my ML and am trying to find that. I would bet the GL and ML have the same code...
