The following has now happened twice - last Friday and again today. In both instances my car sat in the underground parking garage while I was at work all day. But it did not happen over the weekend at home when the car was plugged into the HPWC. I get into the car to go home and initially all screens are dead and then the dashboard says: ! Systems Are Powering Up Press Brake When This Message Clears The car is dead quiet as nothing is running, not even the HVAC. I try pressing the brake and nothing happens at first, but after a minute or two the car does turn on when I press the brake pedal but the 17" screen stays dead. I try to reboot it by pressing the two scroll buttons but nothing for a few minutes. It it is eerie driving the car with the main screen dead and no backup cam or parking sensors. Finally the screen comes alive - I am not sure if it was due to my reboot or not. But still things are not right - the temperature indicator is "stuck" on the right hand side of the dashboard - even when I change that display to the clock or media, the temp still displays on top of what should be there. This also persists for a minute or two. Finally that clears but the media in the right half of the dash does not display Album Art, even though I am playing Slacker which always displays album art. This finally corrects after two hours or so and a couple of stops. Has anyone else seen this recently? Could this be an issue with the 12V battery? There are a few threads here with people describing similar issues but they are all fairly old and are prior to 7.0 - i am on 7.1 something.
