It surprises me that more owners don't crow about how great the standard Lexicon sound system is on this car. I've got two teenage daughters so I listen to a lot of music on Sirius Satellite and bluetooth streaming from their phones and I've come to really appreciate and enjoy the wonderful quality. I listened to several different high end upgraded entertainment systems when I drove the Volvo S90 with the optional Bowers & Wilkins system, Lexus Mark Levinson option and the Bose 3D system on the Audi Q7 and I liked this just as much. Most of the controls work well and are intuitive, sometimes the pre sets controls confuse us. My girls love to be able to control the system from the rear armrest console.
