This paper discusses the underlying connectivity architecture that enables the car maker to bridge the life-cycle between the automotive industry and the portable consumer electronics industry. Universal connectivity requires a physical link for communications, a link for audio, an external antenna connection, a power supply, and an adapter for secure device mounting. In order to link devices with disparate operating environments and physical link technologies, the connectivity framework includes a link independent communication abstraction, an application layer service advertisement and discovery protocol, mechanisms for service management, security, and software upgrades.
