You may not have one. The Nats isn't one specific unit on later models. It is an amalgamation of ECU, key chip, and immu, on the steering lock barrel. This is certain for the 2nd facelifts. Maybe a 1st facelift owner can help more.
Thanks for the reply's.
Looking at what is listed on ebay, the replacement "nissan 28596 9f97 cont unit-keyless box" differs from what's in the car.
If they looked the same I might of given it a go.
