There are two types of shortcuts in Android. One performs an action in an app (navigate to a specified destination, start a music playlist), the other just starts the app.
In CarHome Ultra you can set both types of shortcuts:
To set a application shortcut (start an app): tap a empty button –> tap applications –> pick the application you would like to launch.
To set a action shortcut (performs an action in an app): tap an empty button –> tap the shortcut type you would like to set (like Contact) –> an application dialog from the app you picked should open –> complete the details for the shortcut (for Contacts you would pick a contact) –> CarHome returns with the shortcut button set.
