Worst-case scenario these days is not too bad either, you'll get an aux connector or somewhat stable Bluetooth (if you set it up once and avoid doing anything other than play/pause/next). Yeah, from the software engineering point of view it's slow unreliable crap, but as a consumer you have little power to fix things.
So my cars are always about 5 or 6 years old when I buy them. I optimize for price and costs of running and maintaining them. What's important is that they handle well, brake as they should, be reasonably safe in case of crashes and that's it.
Infotainment and navigation, I put my phone on a holder and I use it. The car could be a dumb one from 70 years ago and I wouldn't notice. I only use Bluetooth to make hand free calls. If it had no Bluetooth I guess I'd have to find some solution for a noise canceling mic.
By the way, my current car came with a version of Android auto that Google stopped supporting the year before I bought it and the manufacturer never updated the car. However I don't care, my phone is always updated and it's exactly the same UI I'm used to when I'm not in the car. This beats having to learn two of them.
(this car pre-dates the emissions scandal, I checked.)
