f700bt connection to Alpine PKG-RSE2 overhead

[sun_dance]

I've got a question related to displaying video to and from and overhead DVD player. I currently have a f700bt and want to connect it to me overhead DVD player/monitor (Alpine PKG-RSE2). I want to be able to display video from the overhead to my f700bt, which I assume should be no problem throught the AUX1 cable. However, the big question is if I have video (through my ipod) playing on my f700bt, can i view that on the overhead? If so how? Can this be done through the existing connection between the two units or do i need to use the S-Video or the AUX 2 connection?

 

Thanks
