i am consolidating all of my questions here. i posted various replies to topics, but to get to the point i thought it would be best to have it all laid out here.

i am looking to add dvd functionality to my front backup camera screen. i have an 09 se without dvd and without nav. i plan on adding an aftermarket dvd player if it is possible and easy to get my idea to work. so here are some questions. can anyone provide any answers to any of these? and i promise, i have spent hours upon hours looking through posts for these answers, so unless you are ABSOLUTELY sure an answer is in a post you reference, please refrain from referencing other posts. I have read all night through refered posts and havent found the answers. Thanks in advance.

1 - what is required wiring wise to tap into backup camera or aux to have dvd playback? is it possible? can anyone provide step by step? what would the cost of these mods be? keep in mind it is a NON dvd and NON nav system and i will be adding an aftermarket standalone dvd player. I want to keep oem stereo and dash functionalities.

2 - if this is not feasible, can i go to a do-it-all system like the Pioneer AVIC F900BT? Since this system would replace my current stereo setup, i would lose my air conditioning on dash settings view, tire pressure monitor, etc correct? i would also gain bluetooth, dvd, nav, and should be able to convert back up camera and steering wheel controls correct? are there any other HUGE capabilities i would lose doing this convert that i am not thinking about?

3 - if i am forced to go the AVIC route, has anyone seen 09 double din kits? i cant seem to find anything on our site or on ebay/yahoo, etc.

4 - once i have either tapped into stock or replaced with AVIC, wiring rear headrests or drop down should be fairly easy right? nothing more than tapping into already established signal?

Thanks in advance for all of the help. Hope some of you guys have some insightful answers.
