*HELP WITH COMAND SYSTEM* ENGINEERING MODE ON 2007 E 550 (US MODEL)
I have read several threads on a few different forums for advice on getting into engineering mode on my comand system and it seems non of the codes that were listed worked on my car. Any advice???
The reason i'm trying to get into engineering mode is to see if my unit will play DVD's.
Thanks
