Hardly, although it is nice to have up here.
BMW, Mercedes-Benz, Audi, etc. have had this as factory equipment for many years on their vehicles; very common on European vehicles. My E38 has 'em and I love it, especially nice when it's rainy and all the dust and muck from the roads get all over the headlights.
The BMW system uses high-pressure jets where Mercedes-Benz uses that and sometimes implements mini-wipers. Either of these would work well on a Pathfinder.
Do keep us posted on your progress.
