Carplay is an absolute necessity on whatever I have next. Once you get used to it, the inbuilt nav is inevitably inferior; phone software updates all the time, car firmware is set probably a year before launch and stays the same until the facelift, usually. Tesla being the notable exception.
One of my friends has a GR on order, but he's specced the convenience pack. That has:
JBL® Premium Sound System
8 Speakers
Toyota Touch® 2 with Go Navigation
Voice recognition
Front & rear parking sensors
Rear Cross Traffic Alert with Brake Assist (RCTA-B)
Blind Spot Monitor (BSM)
Head Up Display (HUD)
Illuminated entry system
UV Windscreen
The only thing I think would be useful in that is the parking sensors, because the body is quite bulbous below the window line. Circuit pack all day for me.
ETA: but if they'd thrown in a rear wiper with the convenience pack, maybe I'd have been swayed...
