I did this setup from Chooks TV tuner and a cable from Chris Rogers. Basically each Headrest has it's own DVD unit in it. Both of them also have outputs so they play DVD's through the front, complete car or individually......both headrests with all the wiring cost me $310 delivered....then I had to by some RCA's, Chris Rogers cable which was about $70-$90(cannot remember)....and the TV unit from Chook....the whole lot was about $750. There is also a slot left to run another satnav or Ipod....+ the is the reverse camera setup.Pic below.
