My blazer doesn't have android auto either... where are these usb things, I might be interested. I really want my phone to respond to 'ok google' not the car saying 'this needs a subscription'

Annoyingly "Android Auto" and "Android Automotive" are completely different things.

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.

These cars are sold with data plans which last quite a few years. What model year is your Blazer? I think that my Equinox has app access for 3 years and maps / google assistant for 8 years. I've tested tethering with my phone and it works with that, so I have a path forward once the built-in subscription lapses.

This is the one that I saw: https://evplay.io/shop/ev-play-lite-gm

It's kind of expensive, and there's a non-zero chance that GM does something to block it.

2024. I refused their privacy policy, so that might be why I'm getting nothing. I don't drive much so I'm worth more to GM than they are to me.

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.

Must have a faster CPU than my Polestar, where Android Automotive runs like a first-gen Android tablet, it's awful

It's actually quite fluid and mostly lag-free.

I've dealt with a lot of cheap android devices over the years, and GM did a good job with this one. It kind of sucks knowing that they could flip a switch and turn on AA/CarPlay, though.

Maybe the CPU is regular speed but it seems slow compared to how fast your Polestar is :)

Those are sweet

Yes, yet somehow with over a year of ownership I have not had one stoplight race. I don't even need to go over the speed limit... I can do 0-50km/hr faster than a Corvette and that's sufficient demonstration for me... but without the ability to rev an engine nobody feels threatened enough to engage.

Either that or everyone's just too engrossed in their phone to consider their ego at the stoplight anymore. I should have just bought a minivan, cars are over

Golden age of drag racing was when cars were simple and teenagers rebuilt their own engines, blueprinted everything, added some custom mods, and then raced each other.

Nowadays with automatic transmissions and EVs, you just buy something and step on a pedal, that's not much of a sport.
