The first picture is a 12v outlet. BMW (and most bikes) uses a smaller size than car standard. You can readily find a converter/extension cord to bring it to Car Size Cigarette lighter size.The 2nd situation, makes no sense....the bolt is not pressurized. I suspect you're just hearing lock tight breaking free....I've removed mine with no issues. IF something does come squirting out of it when you remove it, be sure you're filming it...I think we'd all need to see it to believe it! Good luck!
