As I understand with NTG5.0 you need to replace the whole INTC ATOM infotainment box if you want Carplay.

unichip-tec.com and incarpassion.com at least claim to be able to provide such box. I'd like to understand what my options are and how do they compare, which one should I buy? If I can't get information about specific units and their quality are there at least known good vendors providing such devices? Are any of them available from EU or is China direct my only option?

If I do this, will everything else continue to operate normally, like surround cameras?
