Jazz Hybrid 2014 questions

[orion]

Hi,
I've just bought a Japanese import 2014 hybrid (replacing a 2010 petrol car that has done 190k miles) and it's fine, but I do have a number of issues.

1. Radio security number. Can anyone tell me how I can interrogate the radio so it will tell me what it's security code is? I have looked on YouTube but  I always seem to be looking at videos of the navigation system
2. How do I acquire a wheel nut for the alloys?
3. How can I change the language of the displays from Japanese to English?
4. How do I acquire manuals for the car? I have looked online but they don't seem to be of the 2014 car.

I'd be most grateful for advice, thanks

OK deafening response then, answers see below.

1. Radio security number. Forget it buy new infotainment system.
2. You can't , replace wheels.
3. You can't, live with it.
4. Talk to Honda, they can supply manuals for a near equivalent car for £53

It's a god job the JDM vehicle are cheap, but they're not quite so cheap overall as you might think.
