Replacing OEM headunit with OEM Nav?

[Mojave]

Can this be done? Is it worth doing? I'm thinking it would be easy to do? I was thinking of getting an OEM Nav from salvage and replacing my head unit with it.

Has anyone done this?

FYI:

Found a detailed post on X5WORLD (http://www.x5world.com/) that details what needs to be done to retrofit the NAV into an X5.
