Vehicle Context

In context of in-vehicle infotainment, the terms 'head unit', 'radio', 'module', and 'ECU (Electronics Control Unit)' are used interchangeably and refer to a individual device. This device is typically developed and manufactured by an independent supplier and delivered to the vehicle manufacturer for assembly. MeeGo IVI targets head units with a specific feature set that integrates a multitude of rich and integrated functions for audio, video, navigation, etc. Head unit is tightly integrated with other devices in the vehicle [1].

Head Unit Architecture

Inside a head unit, there a typically multiple processors responsible for different functions. One of them will run an instance of MeeGo IVI. As an example, the diagram below illustrates how different audio functions can be deployed within a head unit [2].
