Head unit wire diagram

I am wondering if anybody has a diagram or could at least tell me where the GPS antenna and where the microphone wire would hook to on the back of this head unit. This is a 2018 head unit out of a Toyota platinum tundra. I am working on putting it in my 2007 Toyota tundra limited. Everything is working except the sound which I found out I need to replace the amp to match that year. Also, there is no GPS I’m assuming that connector is the top right plug in the picture I attach. Also when I try to turn the sound up it says check microphone microphone is not connected. Thanks in advance for all your help.
