Some much needed steps in the right direction there, however it's going to be a while yet until Apple Maps is anywhere near as good as Google Maps. I personally prefer Google maps for the multiple stop facility, which allows me to plan precise routes. I also find Google Maps to be better than VW's own maps for the same reason.
Such a pity that Apple won't allow Google Maps on Carplay, but not altogether unexpected.
I feel the same way, I'd buy an iPhone if Apple Maps was as good as Google's offering, and if they upped the resolution to match Android phones. There's a huge difference between 1334x750 and 2960x1440!
I think the new iPhone this year will hopefully address the resolution but I think you're right that Carplay will still only use Apple Maps. - I don't think they could ever use Google Maps as they'd be providing Google with all that juicy user data that they want for themselves. - if the resolution is good, I might be tempted to try one for my next phone
