I'm going to just put this advice out there: When changing a battery or jump starting another car (don't do that, unless it's impossible to avoid)...

Disconnect anything you have plugged into the USB port in the centre console.

I'm still looking, and some of these soldered pins are really small - so are hard to test, but I think I've found a difference between the 2 test boards I have, and it appears to be in the USB area. In fact, I'd go as far as suggesting - don't ever use that port to charge anything. Light weight USB memory sticks only.

(This advice will possibly just be one of those things people repeat, but I don't think it's bad advice. Can anyone with a broken screen confirm they had nothing at all plugged in? I always have a 32GB stick in there.)
