i'm coming and I wouldn't mind a nosey at it

 

No problem. I'll bring it along tomorrow. One minor issue I'm encountering is that when it turns the display off, it automatically enters something Windows refers to as "Connected Power Mode" and appears to be a kind of extra lower power sleep - even if I disable to sleep option. Annoyingly, it then seems to stop communicating/logging with the car when this happens. I think this may be a Windows 10 thing, as the laptop I was using before the tablet did similar. I've made a tweak to the registry, though am yet to test it fully. If if it appears to solve it, I'll post details of what I've done here, as it may be useful to others, especially if it's a Windows 10 thing.
