Hello saabworld, I'm looking at a 2007 9-5 sportcombi aero. I am wondering what audio systems the 2006+ had and what one comes standard in the Aero? I know prior to '06 there was the popular, premium and prestiege. Did these options carry over or is there just one stero option? This car is listed as having 10 speakers if that helps. Any help about the specs of the audio systems and what is standard on the aero is appreciated.
