heated front screen, is it possible???

I was wondering if anybody knew the answer to this, Ive got a late '02 td4 es auto, and what with all this cold weather at the moment a heated front screen would bit a bit of a bonus, now many moons ago I used to own disco 2, and when I had to have a new screen fitted, I was told the wiring and plugs etc. are all in place for a heated screen, so naturally I had a heated screen put in, so I was wondering if the hippos are the same, everything in place etc???????

I am not certain on this but on my Freelander, the wiring was all in place for the heated seats so would guess its probably the same for the screen

A supplementary fuse box may be fitted in the engine bay, and is used for either a heated screen or PTC heater, mentions it in the handbook, so the complete wiring may not be in.
