Hi
I have a really nooby question, but I'll admit that I've never even gone near a car battery before...
I need to disconnect the battery to reset my Blue&Me as the lady has gone missing and I can't change what I'm listening to or anything.
Problem: I don't have a clue how to do that.
If there are any nice people on the forum who could tell me how to do it then that'd be awesome.
I've attached a photo of it as well

to refer to.
Big thank you to anyone who can help
