Apple has added a small but useful tweak to CarPlay in iOS 10.3, giving drivers a quicker and safer way to switch between apps without having to take their eyes off the road for long periods of time. Before the update, users had to tap twice to get to another app in CarPlay: one tap to go home, and another tap on the designated app icon.
Now, Apple has streamlined that process. In the left-aligned dock on the CarPlay screen users will now see three recently used apps, so it's always easy to just tap one and jump directly back into Music, Messages, Maps, or any of CarPlay's other apps. Prior to iOS 10.3, the CarPlay dock had just one app at a time in this area.
The slight UI tweak should make it easier for drivers to switch back-and-forth between navigation and entertainment apps while in CarPlay. iOS 10.3 includes a number of other updates on iPhone and iPad devices, including changes to the app launch animation, Find My AirPods, and the ability for developers to update their app icons at any time, without needing to include the artwork change in a full update on the App Store.
