Pulling my hair out
I have an E250 2011 C207 Coupe with an Audio 50 system, I'm trying to establish the full version for update purposes (maps).
I have no USB/SD Card slots, no aux input of any kind.
I do not know what NTG number or anything else I may need.
I do have a navi button a single CD/DVD drive and a fixed screen.
If anyone could give me help before I lose what little hair I have left.
