> ... Porsche said it's going to move ahead with Google Built-In as an interim solution
That's kinda weird as Porsche moved from QNX (say for a 2013 Porsche) to Apple CarPlay (starting from 2017 or something?). If you buy a brand new Porsche today I'm pretty sure it comes with Apple CarPlay.
Maybe this is about more than just the infotainment system?
