satellite radio for 2011 9-3?
 

Hi folks, we're new to the saab family, just bought a really nice 2011 9-3.
I'm looking to add a satellite radio to the factory sound system. Some of the local sound shops tell me it's impossible. I did some googling and didn't find much. Anyone have any ideas on how to get this done? First preference would be to add factory equipment. Second would be some after market equipment. What have you guys done?
Thanks!
