I finally finished hooking up all the media for my car. The one problem I'm having is with the micro sd. It plays the video perfectly in the front seat but will not send the video back to my headrest monitors. I set dual zone to mirror av and still nothing.

I know the video out is fine because I can send video from my iPhone back with no issue. How do I enable the SD card to send video out from the video out? This will be really helpful so I can use my iPhone for music and the sd slot for the rug rats in the back.

did you check the manual? this might be a limitation. I think only video in signals (like iphone/ipod) or dvd/divx video played on dvd will mirror out to other video outputs.

That doesn't make much sense. Why would the SD slot be any different than the DVD? Especially considering neither a supposed to be played while driving up front.

it's how video is produced and routed inside the unit..

dvd/divx go through a separate hw decoder chip which outputs to a video mixer, as does the video inputs. this can be "mirrored" to the rear outputs.

the stuff on sdcard is decoded in software and will only overlay onto the front/main screen

at least that's my best guess... thought i also recall somebody talking about this here as well
