Abstract
Modular auxiliary processor circuitry, capable of performing telematics services, including wireless communications, diagnostic assessment and reporting, location based services, and internetworking, couples with a vehicle head unit through an auxiliary processing module interface. When so coupled, the auxiliary processing module circuitry can perform tasks, services, functions, and aspect that a lower-capability processor of the head unit cannot perform as quickly or as efficiently, if at all. When the auxiliary processor module is coupled and active, its display output can couple to a display device either permanently fixed in the vehicle, or portable and mobile with respect to the vehicle, through conductors or a wireless link. When the auxiliary processor circuitry's output couples to the display device software running on the head unit, or the auxiliary processor module, may decouple the head unit from the display device unless a user interface requests its services, such as tuning an AM/FM radio circuit.
