The car just received the latest Volvo over air software update - v3.7. The car has twice had the driver's display screen lose its ability to display the map between the speedometer and the tach (map image pixiilates and display goes white) and then the entire display goes blank. When this failure mode is active, I have had to use Google maps or Waze on my cellphone to determine my actual speed. The driver's display screen does eventually reboot.
