Zooming in and out on the map is a disaster on CarPlay compared to the phone google maps app. The fact that you can’t keep the map on the cars screen while using other apps is also frustrating and a weird design choice. I’d consider that a killer feature over just using a phone but they chose not to do it. I only use CarPlay in rental cars because it is better than figuring out whatever half baked solution the manufacturer came up with. But for my own car I’m happier with my phone on a mount.
