A new software glinch – I think. To date I have not had any software performance issues with the infotainment-system that have popped up on the various forums until now. Three times over the last two months, the SIRUS radio would not work. The symptoms only occur when you first start the car. The display, channel selection control and visual indication of volume control all appear to be normal but there was no sound. I could hear an AM station or FM station but no satellite. Turning the system off and on had no impact. After a 15 minute drive with the system off, turning the system back on had no impact – still no satellite radio. Sound from the SIRUS signal returned during the next restart. Anyone hear of this kind of issue.
