After a long search, it turns out that this system can’t simply be updated via software to include CarPlay or Android Auto.
However I found an alternative which is decent, but not perfect.

I’m not sure if there are other systems like this out there, and I have also yet to try this personally. But it’s a good workaround if you want to try it yourself.[br]
