Sensus and CarPlay - features

[Farrago]

I've got my new S90 arriving next week, and I'm trying to decide if I need the specific CarPlay feature enabled or not (extra £300). There's some suggestions that Siri works without CarPlay, but it's not clear.

What you do/don't get with the standard Sensus interface compared to adding CarPlay? Siri, notifications, etc...

Agreed about not texting replies! My mate's Skoda reads texts out and he can reply via voice (Siri?) so I'm hoping I can do the same without needing CarPlay specifically. Will find out next week
