The point you make about the USB socket playing up... Mine has been causing my headaches for ages and I could never work out why. Sometimes it would work without issue, other times it would connect/disconnect every few minutes, seconds, hours, whatever. It did it so much sometimes my phones security app would lock the connect out sometimes. I then noticed on a dirt road that it was happening constantly, especially over bumps. I wriggled the USB A end of the cable in the socket and it started to work and stayed connected for ages. then it happened again. I notice that the socket is 'loose' and I'm wondering if there is an issue. I'm trying to find out how to dismantle the centre console and look at the connections behind the socket. Hopefully it just needs pushing together. Any ideas where I can get diagrams, parts lists and how-to instructions for taking the console out? I should mention that it happens to all phones connecting to the USB socket (Android and iPhones), I've replaced all the cables, reset the system, updated the phones, etc.
