possible to loop the video out to video in so you can see the video while driving?

? I'm confused....why would you want to do that? why not just show the video directly on the screen rather than loop video out to video in?

Or are you asking how to do it so you can watch the video WHILE the car is moving? If so, then just do the bypass

yea that makes no sence, since the units are not dual zone, if you did run the video out in to the video in, if you select the video in source then the picture would be black since the unit would not have a source to play, just a loop of nothing, i think you just want to do the bypass
