iOS 12 Beta ( good news and no news )
Me ( iPhone 6S 128 ) 8 inch harmon kardon with Nav.
When iOS 12 final release hits the iPhone apple car play users will supposedly get to use additional navigation software including Waze and Google Maps.
Yesterday I upgraded my iPhone to iOS 12 beta. The upgrade went off for me without a hitch. The phone is noticeably faster! Today I cautiously tried it in the car, and am pleased to report that it also worked flawlessly.
Just to be sure I deleted the car stereo in my iPhone and the head unit and phone found each other again in seconds. Much faster than ever before! In fact the whole phone is something like 40 to 60 % faster.
The non-event is that no new apps have been green lighted yet. No google maps, yet.
Apple will probably let this happen when the new iPhones are announced in the fall.
