1) When I turn the engine off using the on/off button, the radio and dashboard lights stay on. So I have to push it again to turn it off completely?? Is there a way to just adjust it so the button turns off everything the first time?
Same thing here. I am used to it now. This was not the case with my 2006 750i
2) I also have to open the car door by pulling on the lever twice. Can I just pull on it once and have it open? All this extra effort seems crazy to me.
I don't have to do it twice.
2) When I wear my sunglasses while driving, I can hardly see the pop up display. When I set it brighter, I can see it better but then it's really annoying when my sunglasses are off. Any trick to this?
Yes. Head up display does not work with certain sunglasses. I learned it the hard way. I took it to the dealer and they gave me a loaner. After few hours they told me, they fixed it by reprogramming the car. Pickup the car at night and it was fine. Next morning it was gone again. Then I realized it was fine all along. Glasses were the culprit. Manual says that.
