Why did my RADIO, on-star, memory seats, just quit working all the sudden? on 2007 Saab 9-7x

I was listening to my satellite radio, and switched auxiliaries to play my ipod when all the sudden I didn't have a radio, On-Star, or my memory seats. I am always listening to music so not having one in my car for six months is driving me crazy. What can i do to get it fixed?
