T.K.O.

My black 2002 GS300 has no navigation.

I want to get a nice headunit that pulls out into a screen for watchin DVDs... don't care about navigation really, though it would be nice. I also want to get headrests with the screens preinstalled. I've been told I'm apparently sarecrowin' it cause I need a "brain" as well. I'd like to go as cheap as I can without seriously sacraficin quality. I have a buddy that works at the install bay at stereo warehouse so he'll be able to install it all for me and maybe get a good deal on the equipment.

So I'd need a headunit, 2 headrests, and a brain.

How $$low$$ can we go?

(Thanks in advance for all the input, i'll be checking back frequently.)
