Recently, when starting my 2014 HSH limited in cold weather, I've gotten a very brief glimpse of a screen on the Nav unit that has something about "Warning: battery discharge..." and then it goes away. It's happened twice in the last few weeks after parking the car outside for some hours in the cold Chicago weather. Since the car is garaged at my house, I never see it there - only after its been soaking in the cold for several hours and then started. Does anyone know what this screen says in its entirety? As I said it's only appeared very quickly and then its gone. I'm hoping its not a harbinger of something bad developing.
