I have a base 2017 and installed just the mirror in it. My car did not have a wire harness for the mirror from the factory so I had to buy one and run the cables myself. I looked into buying the kit and even downloaded the installation instructions but I decided to replace the factory stereo and run my own camera.
Here is a link to the instruction booklet that comes with the kit:
