Audio Systems: XM Factory Install--2004 Nissan Maxima, 2004 nissan maxima, nissan maxima

Question
The factory system in my Maxima has a button for Satellite (SAT) However, when i bought the car used it had no manuals. I assume along witht he Navigation unit I could install, I could use this for XM orSirius. Correct? If so, what do I need to activate the factory equipment--antenna, etx.  I know I must subscribe.  When I talk to my Nissan dealer I get, let us call you on this.

Any clue?

Answer
you need a xm tunner from nissan about $350.00 or more
nissan bracket ,nissan wiring,and the xm antenna
or you can use one of the portable units and take it home and used it at home or work also  
you need the aux input interface for nissan
