The anti CarPlay stance is a real deal killer for me. I put an aftermarket radio in my Chevy Express to get CarPlay, and have a long history of Chevy, GMC, and Buick ownership, but this one blocks me from buying a new GM car.
We bought an F150 Lightning instead of a Sierra EV mainly because of this. I'm not interested in 'cars as a service'.
Honda Prologue is an option if you really like the Ultium SUVs, sadly only a Blazer sized rebadge and no Equinox.
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 have a blazer ev without it and I agree it is the biggest negative. If I drove 8 hours a day their onstar is better, but if you use a car a reasonable amount it isn't worth a subscription (or setting everything up that is already in the phone)
Honestly I'm an apple guy and felt the same until I drove their Blazer EV and loved the native google maps. This is way better than projecting from phone. The native integration knows about car's battery state all the time and auto-suggests stops. Any native map in car do they but they usually aren't good quality maps. In GM's case, the native maps are google maps. I can also sign in on my google account and I don't need internet to use it (in case I'm in a remote area).
I feel I want every car to have native google maps now.
I've been satisfied with Android Automotive on my Equinox EV. I did see that there are USB dongles which can allegedly add Android Auto to the car.
