i want to put a dvd/navigation system in my dash in place of that led screen. i really want to keep the lcd because of the ac controls and all that other nonsense trip comp. etc. I dont want a flip out screen or anything like that i want to put a screen in the hole the lcd screen came from. Do you guys have any suggestions as to what screens will fit into that hole and good navigation systems that i can use with the screen (BIGGEST ONE POSSIBLE). Should i gut the bose radio out of the dash and put something in there ( i hear its hard to get a dash kit)or should i put like a ps2 or something in the glovebox???? IM OPEN TO SUGGESTIONS GUYS PLEASE HELP ME OUTT!!!!! I WANNA GET THIS DONE ASAPPP any particular models and stuff would help me out a lot.!!! thanx

IS it hard to install this stuff yourself???

ALSO i have subs wired through the factory amp in the trunk rather than through the dash. if i chaneg the headunit and put a dvd navi system is that gonna effect the subs??
