Nissan does make an IPod interface for some models (Altima, Frontier, Titan, Murano, Versa, etc) that gives you control of your IPod from the radio and steering wheel controls.
Example: 07 Altima (look under Audio)

However there is no listing for the Rogue yet. Keep checking with you dealer to see if this becomes an option. The kit alone is over $200. Then you have to add installation costs.
I can see why Nissan has gone with AUX inputs instead. Much cheaper and they're universal.
