Yes it's the actual CarPlay mirroring.
Yes I can control phone functions through the touchpad (through CarPlay not the Lexus system)
I ordered a 3 mtr Mophie usb – Lightening cable off the Apple site. I got them to use it and got them to chase the cable into the centre console. Radio, Podcasts and music all through Car Play. Once you get used to apple maps using siri there's no turning back.
The phone charges using the built-in centre console charger plate.
I absolutely love it.
