In my humble opinion: if I’m buying a new car, for the comparable price point I want not workarounds, I want working solutions. Toyota failed to deliver, period.
My main distraction with older vehicles was juggling navigation on the phone (small screen, my eyes are not getting younger!), charger port and finding something not ugly to mount phone so I can drive with minimal distraction. Magnetic base mounts was what I used, marginally acceptable solution overall.
AUX cord? That’s not addressing this use case at all, besides most cars under 5-6 years allow to connect over bluetooth for that.
Android Auto (and Apple’s take) allow to dump phone somewhere in a storage bin, connect it to change cord and forget about it, all the interactions are on the big and conveniently located screen.
I think this type of technology will make car-embedded navigation systems obsolete quite fast, same as it happens to the dedicated navigation add-on units.
The only situation I still want to go non-Google navigation is when I go to WV mountains, where cellular signal is non-existent. For that I have a $10 application with full-featured offline navigation (with lifetime map updates), once again on my cell phone. I’m still waiting for them to make a version compatible with Android Auto although.
