Is there any secret menu for the engineering in the NTG 3.0 comand. I have seen many instructions posted and u-tubed for all the others but never for this particular version.
I do not think there is one because all other models menu is accessed by a combination of buttons on the command/steering wheel which NTG3 on the S class has non on the command unit. I am hoping posting this will tempt someone to prove me wrong (see where I am going with this)
