Wow, it looks like the Nav system isn*t even an option on the lower trims. It only comes on the Sig. I have to think this is an appalling bad idea. Yeah, I know, just use you phone, but not everyone wants to do that for various reasons (connecting/disconnecting phone every time you get in/out of car, using up phone data plan, spotty/slow data connections in some places on the road, no Nav data on the HUD, etc.). Plus, most people expect a built in Nav system on all but the lowest trim these days. I think this is going to backfire on them, and don*t really see much savings for Mazda in doing it. Glad I got my 2019 model GTR, because this would have been a deal breaker for me.
