Has anyone updated their phone to iOS 10 and checked if everything still works with the MMI?
Excellent, I shall update! Also you're brave running those betas, ran them previously on older dev devices and found them pretty unusable
Updated mine last night and was delighted to find the new "home" button on the MMI- very simple, but makes It even more user friendly than before.
Can you elaborate / post a screenshot? I think this was a frustration of mine when I was test driving as I often got "lost" with no way to get to CarPlay home screen.
