After spending some time reading all of your posts I took the plunge and bought a 570S Spider Launch Edition. The car is awesome, but has spent more time back with the dealer than with me since I took delivery. The car drives beautifully, but when attempting to use XM radio no sound whatsoever comes out of the speakers. After hours of unproductive calls with XM radio and too many refresh signals sent to the car to count, XM radio advised me to take the car back to the dealer for repair. The car has now been back with the dealer for 8 days and they can't seem to figure out the issue. I'm told that the dealership replaced the head unit and still no sound. They then reconfigured the car and the issue persists. Has anyone seen a similar issue?
