I just got a new, 2006 SL AWD last week. I have the Premium and Touring packages, but no satelite radio. I do have a Sirius Sportster radio with car kit. Is there a way to integrate this into my Murano without using the FM modulator capabilities? I'm thinking that it will never be as seamless as an OEM radio, but I don't want to lose the score alert capabilities of my Sportster. Given that I've had the car for less than a week, any help would be greatly appreciated.
