Whole new upgrade for my 2017 SR Unicorn

Been searching and reading and have decided to try and kill some birds with a couple installs.
I'm putting in a new head unit, a few more speakers with a amp dashcams and a radar detector. Thinking with all the cords best do all that shit now while the dash and other parts are off for a professional to do. My longbed is stock SR no real thrills, like bare bones so it's needed.

Just a couple questions for the spots I'm missing.

I still can't find what's the best LCD screen head unit, but like the Alpine or

$1,200 Pioneer DMH-WT8600NEX 10.1" Digital Multimedia Receiver - Wireless Apple CarPlay, Android Auto, Built-in Bluetooth, WiFi and Amazon Alexa, Floating Capacitive Touchscreen, Single-DIN

Pioneer DMH-WT8600NEX

Do I need to do anything different or missing for a GPS/Sirius uplink?

Looks like I'm stuck with the stock front steering wheel that has NOTHING on it for anything new like a new head unit. Toyota say i'm shit out of luck, called a few dealerships on replacing the steering wheel with more bells and whistles.

I think that's all I need to do while I have the dash cracked open.. LOL

 

...any suggestions?
