Ok,
I am Guessing that you dont have TV so you look at this one here

that will give you video input that you can use for DVD video game or other.
You have 2002 so iam guessing MK III nav, does not take DVD and no perspective MK IV is what you want http://www.europeanautosource.com/pr...roducts_id=942
I dont know what screan you have but you can find 16:9 here http://www.europeanautosource.com/pr...roducts_id=943
and as everything else it can be found on e-bay, watch out for faulty units.
Good Luck
