DUD

I bought a Flex over the weekend. The car is comfortable. I like it. However, I noticed a couple things about the dvd system that do not follow the owner's manual: 1) The OM indicates the dvd player has three different control modes: locked, local, and full. Pressing the 3 and 5 preset buttons only cycles between locked and full on my Flex. Has anyone seen/resolved this problem? 2) The OM indicates the dvd player can be controlled from the front audio system controls. I can select the dvd chapter with the seek buttons, but I cannot pause/play with the big tune/pause/play radio control knob. Has anyone seen/resolved the issue? Note: I do not have the nav system, but I do have the Sony system and SYNC. Thanks.
