When I tried Android Auto it actually took over my car's infotainment system and made my phone slightly slower having to drive another screen? I dunno it's been years. I just don't see the value in it personally.
For maps, having up to date maps is an enormous relief compared to relying on the outdated maps that came with your car (at least in my experience).

Yes. I prefer it that way. The car's default infotainment system might as well not exist for all I care, since I prefer the Carplay experience.

I haven't noticed this problem.
