So this is Samsung's version of Android Auto, instead of Google's?
Not really. Android Auto integrates your phone's capabilities onto your car's info/nav display. This new Samsung UI feature only launches an app on the phone itself. Android Auto has it's own GUI which appears on your car's display. At one time (several years ago), that GUI could display right on your phone screen. But then with so many newer cars being capable of running it on the car display, they decided that for legal (liability) reasons, they no longer wanted to support a "car mode" that displayed right on the phone.
However, I have no choice; I can't run Android Auto into my car's info/nav screen. But all this Samsung feature is doing is 2 things:
1) Detecting bluetooth and launching an app (SiriusXM);
2) Reading incoming texts aloud.
But if you combine this with Google commands (OK Google), I can get my phone to do whatever I need.
For comparison, Android Auto looks like this on a car screen
With the new Samsung UI setting, I don't get a customized screen on my phone. I get a brief notification that it detected my bluetooth device, and that it's launching car mode. And then it just starts the SiriusXM app. If I receive a text, I get a notification, and then it reads the text. If I want to reply, I have to use OK Google to do a voice-to-text. I also have to use OK Google to launch navigation, or change channels on SXM, or check the weather, or make a phone call.
My car
does have navigation, but it sucks. Even the 2020 Subaru we had was equipped with a useless nav system. None of the bult-in nav systems have speech and place recognition like Google. On my car, I have to spell things one letter at a time, starting with the state, then city, etc. On the Subaru, you first have to give it a category for what kind of place you want to navigate to. And the speech recognition is bad. None of the cars can do speech-to-text.
