Android Auto is where you can connect your phone to the car and your phone projects onto the car's display with apps and navigation.
Android Automotive is when the car itself is running Android Automotive for its infotainment OS, meaning it has access to a limited Android App Store to install apps natively into the car's infotainment system and you can sign in with your Google account.
Some cars with Android Automotive also support CarPlay and Android Auto on top of it, but GM has decided to disable those features, meaning you have to use the built-in Android Automotive system to manage your media streaming apps and pay GM for the data access plan.

It's kind of expensive, and there's a non-zero chance that GM does something to block it.
If GM tries to block it there are a number of ways a lawyer can fight back and likely win. The Magnuson Moss warranty act was historically written about car radios for starters. There are other consumer protection laws as well. You need a good lawyer, but I suspect they will take the case for the expected gains in the return lawsuit. If I were them I'd get a lawyer to write this up in a "white paper" - It would be a few thousand, but it is also something GM will likely see if they think about doing anything.
I do wonder what the outlook for that is now, they were supposed to be a shorter term bridge until Honda had their own EVs but Honda recently killed a bunch of EV plans so maybe the GM partnership sticks around a while?
I feel I want every car to have native google maps now.
CarPlay does this on my F150 Lightning. It manages state, preconditioning when routing to a charging stop, will suggest charging stops as I'm routing, etc. etc.
There's really nothing special about GM's implementation IMO, except that they charge you monthly to access it.
I'm a huge fan of the Bolt, and I love my 2019. It's a very practical car, and has surprisingly decent range.
