I got a 2010 c300 with UMI NAV+4, no MM package. I was wondering if i can add a back up monitor to my current setup. Also, is there any way i can have the screen display chinese characters when using either the USB or Ipod integration kit?

 

UMI does not allow it any better over the standard head unit without UMI.

Can you explain what would you have on the display that would be of interest for the rear passengers? After all it does not play any video.

 

i'm not looking for it to play videos. i just want to install a back up camera for when i put the car in reverse.
