This document introduces Android Auto, its goals of providing a standardized in-vehicle experience for users and developers, and its technical architecture. Key points include: - Android Auto aims to solve problems with the current in-vehicle experience like a lack of customization, standardization, and developer tools. - It builds on earlier projects from 2005-2014 and was publicly announced in 2014. - Its approach includes a unified Android platform, standardized protocols, and easing integration for auto manufacturers. - The technical architecture involves Android Auto apps and services on phones/tablets connecting to an in-vehicle unit via a linking protocol to share media, notifications, and sensor data.
