I just purchased a 2005 gx470 with mark levinson rear entertainment system. The system has a set of rear audio and video inputs in the center console that allow you to input your own video device. I used the left and right audio inputs to connect to my ipod with a simple ipod adapter. The rear system menu displays am/fm/cd/dvd and adds a video option. This is the auxillary inputs. This allows me to listen to the ipod in the rear on the wireless headphones. Does anyonoe have an answe why this video input option does not display on the front navigation unit.

You cannot watch any type of video on the front navigation screen unless the hand brakes up.
