Anna (which I never use) and Radio Next (which I never use) are mandatory button mappings. Why? Neither is vital to gameplay and when I’m trying to fit in telemetry and manual shifting they are a massive pain in the fundament. I have to give up forza link options (which I WOULD use) because I’m required to save buttons (which should be context related anyway) for things I have never and will never use and, most importantly, are not in any way needed to play the game. Frankly, if you removed the entire radio system less than one percent of your players would care.
