In the future Apple CarPlay can be accessed wirelessly

Apple CarPlay

In the midst of tight competition against Android Auto, Apple CarPlay seems to act more aggressively through a highly anticipated feature, the ability to operate wirelessly. Through WWDC 2015 stage, Apple has announced that along with iOS 9 later, CarPlay will no longer need a cable to connect your iPhone to the car dashboard.

Previously users must connect their iPhone to the USB port of car's head unit if they want to access the CarPlay. Going forward, the applications that are stored on the iPhone can be used directly through a compatible car's head unit wirelessly.

At the same time, Apple also opens an opportunity for automotive manufacturers to embed their applications into CarPlay. Thus, the car owners no longer need to go out of CarPlay to access the companion app of their smart cars.

Apple also explains that CarPlay will be implemented on the car's head unit that's packing diverse screen sizes with different aspect ratio, including the high-resolution screen. This step may be taken to increase the interest of automotive manufacturers in adopting Apple's connected car platform. 

One thing to note, the CarPlay update also requires new hardware. This means that the owners of the cars which have been compatible with CarPlay need to replace the head unit.
