The NAV system will NOT be able to play DVD movies without some modification. This topic has been discussed within the last week on this message board. I can't remember exacly where, but look around because the string I am referring to will help you know what you need to do to make it play DVDs or PS2 games, etc.
As far as the smoked tail lights are concerned. I just got back from Longo Lexus in El Monte, CA. They have at least 15 2002's. ALL of them have the the smoked tail lights. You asked about the dark colors. I think the new tail lights look particularly good on the dark colors. I used to think the black IS looked like a modified civic with the white lights. Now it looks a little more upscale.
