Can someone help me i just bought a 2010 ls460 an im just hearing about the ml system how do i no if i have it also how do i make video come from the navigation unit its suppose to be fully loaded but i tried a dvd an it didnt work

look on your head unit, if it has ml it should have the mark levinson logo right below the dvd slot

and if you have that, you have dvd changer. put in the disc, make sure parking brake is engaged and car in park, it will play
