I've searched the forums for this answer and cannot find it. I know that the ML/GL/R COMAND systems are not the same as the others.

I upgraded my Navi and COMAND software once in 08 (have an 07 GL), but i have not upgraded since. Does the newest upgrade give reverse lines in the rearview camera? I like this feature on our R-class (09) but it also has the newer COMAND system. What features will a COMAND upgrade to the older give me?

Thanks!
