AFAIK, if you don't have a touchscreen you've got Sync 1 (it's the 4-inch LCD). Unfortunately, my steering wheel controls don't work, so I couldn't use voice control to change the input (and replacing the head unit was way less complex & expensive than the steering wheel controls).
I don't mind the touch screen for CarPlay since all the important controls (volume, mute, skip, Siri) have physical buttons, all the unimportant controls are very large and hard to miss, and CarPlay has very few menus requiring more than 1-2 taps; though I had to be careful to pick out a CarPlay unit with an actual knob for volume, since a lot of them just have buttons that you have to mash repeatedly to change the volume. But not having the physical buttons at all would really suck, especially for things like climate control.
