I know all that, the point is modern infotainments do way more than just play music. Look, I wish it was different, but most cars built today have controls in the infotainment that you can’t have anywhere else. Like very specific settings for interior and exterior lighting, consumption metrics, creature comforts, just to name a few. That’s not a simple case of getting the wires correctly installed like it was before. And good luck finding just the right car with a dumb head unit, even simple cars today are fitted with this stuff.
