Does anyone know if the N-bus system on the g35 is the same as on the nissans?

Nissan makes an ipod adapter that plugs directly into the N-bus. If I recall correctly, we have that connector in the trunk with sat ready cars and also behind the head unit

they don't show an image of the connector, to see if it is physically compatible.
