While developer Steven Troughton-Smith has shared several screenshots and a video of iOS in the Car running on iOS 7.0.3, the iOS 7.1 beta currently available to developers offers even more iOS in the Car functionality, including a redesign.

According to Troughton-Smith, it is difficult to access iOS in the Car in iOS 7.0.3, but another developer, Denis Stas, has discovered that it's much easier to access iOS in the Car in iOS 7.1 and has detailed how to enable the feature using iOS Simulator.

Stas details three steps that are necessary to get iOS in the Car running in iOS Simulator with iOS 7.1:

- Download the second developer preview of Xcode 5.1

- Clone https://github.com/zyafa/iOSCar

- Build and run cloned project and follow included instructions

Developers with access to iOS 7.1 and Xcode 5.1 DP2 will be able to give iOS in the Car a try, but non-developers will not be able to access the necessary software.

According to Stas, the current implementation of iOS in the Car is both unofficial and unstable. The iOS 7.1 version of iOS in the Car features a different design than was previously seen in iOS 7.0.3, featuring a look more in line with the style of iOS 7.

As noted earlier today, these design changes may be the result of organizational issues that have affected the development of iOS in the Car. While iOS in the Car can be accessed by developers using iOS Simulator, it remains unclear when Apple might officially debut the feature.
