Strange thing happened to me after updating yesterday. I lost any and all connectivity to the car. The app won't connect and when I'm in the car, Alexa, music, Nav all stopped functioning. It shows 1 cellular bar no matter what. I tried to turn off wifi but then nothing on that pilot panel would react when pressed. I've tried a bunch of valet key resets to no avail. I spoke to customer care a few minutes ago who said they would arrange for a mobile van to visit since he had no ideas. But I need the car for tomorrow so am going to cross my fingers on my 150 mile round trip to take my 95 year old dad to the doctor. Any ideas are really appreciated. Thanks.
