I need some help...have 2018 Perf...today i got this warning message saying MMI not recognized...for Strata, Sport, and Corsa. Car is running fine. I checked my mode buttons and it seems ok. The warning doesnt stay that long. Not sure if I need an MMI update. Ill take a photo when it comes out again. I live about 4-5 hrs away from the nearest dealership. Is the car still safe to drive? Thanks
