Thanks for the reply Richard.
This is the camera I am looking to buy:

I have contacted the seller asking if they had a NTSC version, and I got a reply saying the camera is PAL/NTSC. So I am not sure if it is compatible.
Made an enquiry regarding CGW with my dealer but they are still not sure if they can code it. Is a CGW needed to retrofit the multifunction wheel and LCD cluster?
