CarPlay+VIM+FULL SCREEN HELP

So you're saying if the vehicle is not equipped with WiFi antenna it will not work?

 
It may or may not work properly without a WiFi antenna. Obviously, it's better to have one.
OEM WiFi antenna (part number: 61116816435) costs around 50$. Else you can buy a non OEM one for around 10$.
But as said previously, you need to make sure first that the iphone connects correctly to the EVO, before trying Carplay.
