Can't take out the original DVD ROM player as it is hooked into Engine management info, TV Tuner. Take it out and you loose TV Tuner whitch means the aux in goes, then you have to get rgb convertor to get screen working again.
Best so far is to lengthen wiring loom (4 hours) move original unit down behind glove box and then fit a normal DVD player and run cable to TV Tuner in boot. All beyond average joe's ability, eastern staters need to talk to Chris Rodgers in Brisbane (he is all over this forum) and west coasters need to see brian at Autotainment in Perth.
