Abstract: Additional entities, such as consumer electronic (CE) devices may be integrated into a vehicle electronics system using generic device classes. The vehicle electronics system (10) comprises a human machine interface (HMI), and at least one generic physical and logical interface, A device integrator (20) is connected to the vehicle electronics system (10) via its generic interface and provides connections to additional entities, which may be hot pluggable. The device integrator (20) classifies the connected consumer electronics devices, such as mp3 media players, DVD plaers, gaming consoles, according to their functionality into a set of generic device classes. The integrator translates the individual logical interface protocol of each subsystem group into a generic communication protocol, providing a software or logic driver which is supported by the in car electronics system (10), such that a connected entity may be operated via the HMI without loading any entity specific executable code into said vehicle electronics system. The integration framework may verify the source and integrity so that trusted software is uploaded, to display a specific screen layout for each device class. The integrator may include a USB connection or an FM transmitter for physical adaption to a wireless interface for the vehicle.
