GM's system is built by google and it's not laggy at all. That said, I also wouldn't buy it because I want carplay.

I just want someone to figure out the perfect entertainment system has a volume knob, a radio button, and a mirror phone screen and audio button and thats it. Bonus points for allowing me to choose to mirror over wifi or over a usb that also charges.
