This feels familiar - I have a 2014 Volkswagen with touchscreen, bluetooth audio, calling, contact management, MirrorLink, etc. - about 1 out of 10 times upon starting the car the iPhone won't be able to connect to the car. It will only work again if I stop the car for a few minutes and start it again. Of course there are no VW software updates to be found and I'm not interested in bringing my car in to be serviced for this. All I want is Apple to be the software vendor of my car. However using CarPlay of course requires me to buy a new car. There's no upgrade path which is very, very disappointing.
