OMG rental cars AV systems and bluetooth are the bain of traveling ... my travel buddies and I will spend up to 5% of our entire trip talking and dealing with this pain cause we have iPhone and or Android.

The UX is painful and now bluetooth is controlling even more portions of the car ... hilarious yet dumb and concerning.

I'm about 50/50 with rental cars working with CarPlay easily (ie, the pairing dialogs pop up and run without issue).

But, when the pairing fails, I just don't bother. There's nothing on CarPlay that is 100% necessary to use a rental. Yeah, it's nice to have. But, I'd rather do without than waste a few hours trying to configure it on a car I don't own.
