Driving with carplay function is safer and more convenient on the road, because you are able to control music playing, maps and even other apps conveniently by touch screen on the aftermarket screen unit.

Carplay is with Siri voice control, so you can focus on driving and also use the Apple iPhone functions on the display screen at the same time.
