Having it built into the car still seems to be an improvement to me. I'm still yet to see any of these systems actually function at all. My '16 Subaru and Samsung phone both officially support it. But if I try to turn it on, you can take a guess from one of [incomprehensible error message | car does nothing, and phone locks up until hard reboot | car shows a blank panel on the screen until you press the home button] I don't know how unusual my case is, but it seems like there's a greater chance that it would work if there were fewer "moving parts" that had to interface.
