The new iOS 13 CarPlay home screen displays a widget screen. The widgets are as follows:  In the center of the screen, there is an Apple Maps map. In the upper-right corner, there are some quick locations (i.e. home and work) that you can tap to select. In the center-right, you have music and the options to play, go back, or skip to the next song. If Suggestions are turned on (see Changing the CarPlay Settings), they'll appear in the lower-right corner. In the sidebar, to the left, you have a few frequently used apps, such as Apple Music, and the Phone app. There may be more than one page full of apps, so keep swiping left to see more pages. This icon is in the lower-left corner of your apps screen. If your infotainment system uses knobs or other physical control methods, these will work with CarPlay as well. Twist the knob to cycle through the CarPlay options and press the button to select it. Siri is arguably the most effective way to control CarPlay since you don't need to look at the screen while you're driving. You can activate Siri by pressing and holding the Voice button on your steering wheel. If you don't have a Voice button on your steering wheel, you can press and hold the simulated Home button on the CarPlay screen.  With Siri, you can perform virtually any command that CarPlay supports. For example, you could start Siri and say "Call Bob" and Siri will place the call for you. The call will then play through the car speakers. See each of the sections below for details on using Siri with various CarPlay features. With iOS 13, many vehicles now allow you to activate Siri by saying "Hey Siri". You can now use Siri to control many more apps, including Google Maps, Waze, Audible, Podcasts, and more. Siri will also give suggestions associated with your events in the calendar. If your events have an address or phone number associated with them, you can use Siri to get directions with CarPlay. You can still return to CarPlay at any time by tapping its icon.
