First and foremost take away the annoying message on the Nav screen, make it Ipod compatible, make the voice nav recongize a man's voice. My wife can get it to work but everytime I ask for something it does something else. Longer leg room in the 3rd row and I agree with a fold flat 3rd row.
Heated rear seats so the kids can stop complaining when it's cold. And I would also like to see signal mirrors and I go on and on...........
And with all of this missing I still love my 04 GX
