They should apply\nglobal customizations to make the design consistent with their entire IVI\nsystem, as described in\n[Global styling and layout customization](#global).\n\nThey can also customize specific aspects of the portrait reference design,\ntaking particular note of the guidance for the following:\n\n- [Base layer](#base-layer)\n- [Status bar](#status-bar)\n- [System navigation bar](#sys-nav-bar)\n\nGlobal styling and layout customization\n---------------------------------------\n\nPartner OEMs must customize the reference design to reflect their brand values,\noptimize for their display configuration, and ensure consistency across their\nIVI system.\n\nGlobally customizable aspects include:\n\n- [Styling](#style)\n- [Layouts](#layouts)\n- [Interaction patterns](#patterns)\n\n| **Note:** The IVI system includes, but is not limited to: setup screens, home screen, launcher, Notification Center, HUNs, system bars, system apps (such as Media, Dialer, Settings, and Calendar), and components (such as dialogs, buttons, sliders, and switches).\n\n### Styling\n\nPartner OEMs must customize styling of the portrait reference design to\ndifferentiate their brand and maintain stylistic consistency with other parts of\ntheir IVI system.\n\n\nCustomizable styling includes icon styles, font size and weight, application of\ncolor, elevation, and other visual effects.\n\n### Layouts\n\nOEMs should customize layouts only when necessary --- for example, when needed to\nadapt the UI to fit their hardware.\n\nCustomizable aspects of layouts for the portrait reference design include:\n\n- **Location of components**, such as where the toolbar is placed within an app layout\n- **Arrangement of elements within a component**, such as actions within a toolbar\n\n### Interaction patterns\n\nOEMs should **customize interaction patterns only when necessary**.\n\nInteraction patterns in the portrait reference design include those provided for\nnavigation, search, and browse.\n\nSituations where it might be necessary to customize interaction patterns might\ninclude adapting them to specific hardware needs, such as different input\nmechanisms or smaller screens that need to run full-size apps.\n\n### Base layer customization\n\nOEMs can choose the type of apps that can run on the base layer. For\nexample, navigation apps or parking apps.\n\nGoogle Automotive strongly recommends running navigation apps on the base\nlayer and all other apps on the top layer. \n\n\u003cbr /\u003e\n\n### Status bar customization\n\n**OEMs can customize** the following aspects of the status bar:\n\n- **Contents of quick controls**: which settings are displayed in the drop-down menu\n- **Position relative to apps**: whether apps appear entirely below or partly behind the status bar\n- **Default opacity**: whether the status bar is opaque or transparent\n- **Default color** (if the status bar is opaque)\n\n\nApp developers can override the following aspects of the status bar:\n\n- **Opacity** (whether it's opaque or transparent)\n- **Color** (if the status bar is opaque and the app is positioned entirely below the status bar)\n\n### System navigation bar customization\n\nOEMs and users can customize certain aspects of the system navigation bar,\nincluding the comfort controls, notifications, app launcher, and voice\nassistant.\n\n\n**OEMs** can customize:\n\n- **Digital assistant**: OEMs can customize the digital assistant to be used in the car.
