Hello Priuschat! Here is my Install of my Alpine ILX- W650 Unfortunately the ilx-w650 doesn't have a data link port and cannot read things like tire pressure and engine codes but its still supported and i can control everything from the steering wheel. Tomorrow i will upload a video of myself installing this radio into my wife's 2018 prime as well I originally bought 2 JVC KW-M750BT for our cars and the quality was not on par with the ILX -w650 if you guys have any questions let me know. i know this write up isn't great and im sure ive left some important details out but hey i tried. Parts list: Metra 40-LX11 Antenna Adapter Cable Metra 95-8264HG Mounting Kit Maestro HRN-RR-TO2 Harness Maestro ADS-MRR Steering Wheel Interface Pac USB-TY1 Retention Cable Here is the dash kit, it fits perfectly and the gloss black matches quite well Here is the Harness you will have to cut off the two end connectors (Grey & White) and wire them. This is after wiring everything together with the radios harness (for the antenna connector you will have connect the blue cables together for it to work properly) after flashing the maestro i have connected everything together and its ready to be installed into my wifes prime. you will need to go to idatalinks website and input your car and type of radio you are installing, they will in return give you a very detailed install sheet to help you.
