Does anyone have the code to enter the reprograming mode for the Comand module on a 2009 E350 Wagon. I want to turn on the backup camera function.

I tried the code for the 2008 C Class from this web site and it does not work.

I plan to install a backup camers and because I can make entries on the Nav System while in motion I have been told that I may not need the VIM unit -- hope they are right?


Thanks for any input I can get on this subject.
