[HUMMN]

Hi everyone, I have a 2006 H2 SUT and I am looking at purchasing the OEM headrest monitors of either these:

or these: http://www.ebay.com/itm/140593208078?ssPageName=STRK:MEWAX:IT&_trksid=p398 4.m1423.l2649#ht_3306wt_1037

I am in the process of getting an iPad 2 fabricated into the dash of my rig and would like to know if their is anyway I can tap into the video feed going up to the headrest monitors so I can view the iPad screen on these as well? Any help would be greatly appreciated! Thank you!
