Generally agree but they are laying the path to enshitification. You see you can get turn by turn directions on the HUD, but only through their app where they want you to pay $10/mo for the privilege. Same for inputting addresses into their crappy nav system.
So I only use Google maps with Android Auto now, but cannot put the turn by turn display on. Also, who knows what telemetry Mazda is sending home on me without me knowing or wanting them to. Probably selling it to data brokers.
I believe I've heard the newer Mazda 3s have added the navigation into the HUD for Android Auto and Carplay. It's not in my 2020 though which is annoying.
As for selling your data, yes absolutely. It goes to Connected Analytic Services which is an affiliate company of Toyota Insurance. Toyota Insurance Management Solutions (TIMS) is another name to look up. Subaru sells your data to them as well.
