Abstract
Abstract A vehicle user can request emergency or roadside assistance from a response centre by activating a button in the vehicle. A global positioning system 21 is used to continuously store the vehicle location. A cellular telephone network 22 is used to contact a response centre 15 and transfer a data string via modem containing information to assist the response centre in acting on the request. Prior to attempting dialling of the cellular transceiver, a command or set of commands places the cellular transceiver into an unrestricted operating mode to provide the greatest probability of completing a call from the vehicle to the response centre and from the response centre to the vehicle.
