1. A system for testing wireless interaction between a user-interface device of a motor vehicle configured for reproducing audio signals, and a mobile phone, said user-interface device of a motor vehicle configured for reproducing audio signals and said mobile phone being configured for communicating one with the other over a radio wireless communication channel for short-range communications, said system including:
a module for simulation of a mobile phone, including a computer that acts to simulate the operation of a mobile phone,
said module for simulation of a mobile phone being associated in a signal-exchange relationship to a short-range wireless transceiver module configured for communicating via said wireless communication channel with the user-interface device of a motor vehicle acting to reproduce audio signals,
said computer further acting to simulate a portion of mobile phone between audio inputs and outputs and a transceiver module, integrating in a software module a communication protocol including a protocol stack of the wireless communication channel, wherein said protocol stack includes a hands-free profile which enables the user to send and receive telephone calls, said protocol stack also including a SCO link connected for carrying audio signal both in incoming/outgoing calls and in internal sample loops to and from a baseband module through a HCI (Host Controller Interface).
