Hello, I want to put usb charing ports into the blanks next to the cig lighter in the centre box. I've removed the 2 bolts but I missing something, it's moving a little but not enough, bit stuck on where / what to remove next. Has anyone done this before that could give any advice, many thanks in advance :)

I had a look at doing this myself but never got round to it. Have you popped the little try of at the back? Could there be more screws under there near the battery isolator plug?

No need for full disassembly :) I found a small gap to pry the back plate off at the top right.
I've just ordered this: https://ebay.us/m/6WN6I0
Supports proper fast charging apparently, I'll post up more when it's in!
