I felt like I was missing out on
carplay until I had a '18 G80 loaner with the tech package. HATE not having the knob, the smaller screen/UI is meh, and it must have a different processor as it seemed super SLOW. Backup camera takes forever to load and would go black intermittently, adjusting the volume or temp would make the values 'jump' on the screen (instead of smoothly scrolling through like on the 9.2), and I find the nav system in the 9.2 to be great. Like how it plays nav guidance through one speaker instead of shutting everything competely off like
carplay does when nav is talking. And directions in the HUD is super convenient too.
I knew I wanted the control knob and the matte wood but having the loaner for a week really cemented that for me. I would much rather have the extras and forego
carplay.
Carplay would be super great on antiquated systems (like the GX460 we're looking at for my wife, or my in-laws Yukon) but I feel the 9.2 is still very up to date and easy to use. No regrets.
