Hi all, I am back in the x5 club with a 2009 e70 35d. It's a bit rough around the edges but I'm treating it as a project.

What I'd like to know is as so many things were options, such as the usb port in the armrest, is the wiring likely to be there already and just requires coding?

I really want to turn this car into a retrofit monster so any help will be appreciated and indeed, needed!
