Same here. I was 9\10 certain I will be getting the Equinox EV a few months ago. Now, knowing there's no AA or ACP, I'm 4\10 on the EQ EV, and 8\10 on a CX-5.I just received and replied to a GM satisfaction survey based on my email to them about Android Auto/Apple CarPlay. Gave GM a 0 out of 10 and told them that I would be looking elsewhere when it comes time to replace my Volt.
Chevy could have easily avoided that by having both systems. Press an icon to switch to AA\ACP, don't press to stay on the native system. If a $600 aftermarket head unit can do that, I'm sure they could have done it too.
