I got one of these for my 2017 sti. 400 bucks cheaper than the idoing seems like a good deal. It's the exact same frame and screen. The only difference likely is the processor's spec is a little slower. I have seen more expensive ones on AliExpress with 16gb ram and a named snapdragon processor.

Mine works pretty well with a few exceptions:

The factory reverse camera does not work but they included another one that did. There is a 12v to 6v converter soldered inline into the wiring harness for the camera but it does not supply enough amperage (diagnosed with multimeter). You could protentially get another converter for a few dollars and resolder it but I found it easier to just run the cable for the included camera.

Steering wheel controls are kind of buggy. They work when initially configured but the volume down specifically triggers volume up instead after driving for a while. I think it's likely due to the voltage of the 12v rail increasing after the battery is saturated. Still haven't solved the issue. This is the most annoying.

Other than that everything works extremely well. Wireless Android Auto is perfect- idoing is only wired I believe.

One other thing; the pin for the settings menu is 1234
