Hey JJMondesi
Welcome to the forum
I can sort of relate to you since i had a 13' special edition too and had my pioneer avic added to it but i guess yours came with the 4'' screen
you can contact the guys at Sonic electronix for your rear view camera if you want to keep the factory one
And for your steering wheel control you will need a Steering Wheel Control Adapter by axxess (links below)
and for the rear view i had a high definition since the factory camera isnt the best anyways
for usb if you have one on your radio you should be able to run the cable to the glove box
P.s If your are not sure get professional help .
