GM plans to phase out Apple CarPlay in EVs, with Google's help

As others have said, it uses WiFi (set up via Bluetooth).

Bluetooth doesn't support the data rates necessary to deliver the data for CarPlay. As for the "maybe with slightly less functionality" would you take no display? You're basically talking about Siri Eyes Free where you'd have a button to activate Siri on your steering wheel, but wouldn't get much functionality. But I'm guessing you want the navigation to be displayed on your screen, not just a bluetooth audio connection with a Siri button.

Basically, the 1-2Mbps of Bluetooth really isn't enough to drive a display with any decent resolution and I'm guessing that real-world data rates are a bit less than spec with so much stuff in the 2.4GHz band. Microsoft notes that you need 1.5Mbps for 1024x768 and I'm guessing most car displays are better than that today (https://learn.microsoft.com/en-us/windows-server/remote/remo...).

Maybe you'd argue that you'd take 5 FPS and semi-reliability, but I just don't think they want to implement something that's just kinda crappy. Apple doesn't want you going around saying, "wireless CarPlay is garbage." Yes, you might understand a retrofit to a car that doesn't really have the capability, but 99% of people won't. It's not that it's impossible as much as something likely to be way more pain than it's worth. Even if you want it and would be ok with the trade-off, that's not always how products work. Heck, if they did implement it and it didn't work, would you end up using tech support for it? That costs money. Would you post online where your problem-solving becomes interpreted as "Apple sucks" even if you don't mean it that way?

Worse, car manufactures might (and car dealers definitely would) start promising these models as supporting wireless CarPlay. Maybe Apple could deal with official marketing materials, but dealers will say almost anything to sell a car. People would be duped into buying these cars and then complain to Apple that their product sucks. People would be asking online "is this real wireless CarPlay or the fake kind?" The absolute headache!

You can buy an adapter that will plug into the USB port if you want wireless CarPlay: https://9to5mac.com/2023/02/27/carplay-wireless-carplay-adap.... Basically, the information goes from your phone to the adapter (via Bluetooth-setup-WiFi) and then the adapter just sends it over USB. That's way less headache for Apple and probably a better experience since it actually supports the right data rates. I haven't used one of these so you should read up if you want to buy one (or try it out and return it if it doesn't work for you), but this seems like a much better alternative than trying to jam CarPlay over Bluetooth (without WiFi).

I mean, GM did gather the listening habits of 90,000 "volunteers".

That's the neat part, they have aux out. ;)

I'm pretty sure that is what GM's play is here. There's a lot of confusion. They are moving to Google Automotive Services, complete with Android and the Play store where you pick what is on your car. Apple music is one of those apps.

> Subscription services tied to my car and not my phone?

Data Subscription, it is Google play under it all.

> Needing to maintain navigation routes on my car AND my phone?

Google Maps is on both and would likely work as well.

> Being forced to use only built in apps like Spotify instead of “whatever is on my phone that supports car play”? Google Play, how you get apps in next-gen GM Android Automotive would have the same apps.

It works exactly like having a Mac/PC and a phone.

Apple does restrict access to much of their platform for only Apple-based access. There's exactly one company stopping Google or anyone else from building a compatible car system that runs for both Android and ios, and that's Apple. The use of private APIs and preventing competitors from using them, to secure another market (car infotainment systems) certainly should run afoul of anticompetitive laws in spirit, even if it doesn't to the army of lobbyists and lawyers the most valuable company in the world can muster.

By comparison, nothing (not even Google) is stopping Apple from producing CarPlay for Android. All the APIs are there. They could even distribute it in the Play store.

Compare the PhoneLink capabilities between iPhone and Android, vs the macOS integration Apple offers iOS.
