1. A vehicular emergency message system in a mobile vehicle for communicating with a response center, comprising:
- a cellular transceiver having a control input, said cellular transceiver selecting a restricted operating mode or an unrestricted operating mode in response to predetermined commands received via said control input, said restricted operating mode being selectable by a user to affect communication links that are permitted during normal operation of said cellular transceiver;
position determining means for determining a location of said mobile vehicle;
an emergency message controller coupled to said cellular transceiver for controlling said cellular transceiver to communicate with said response center in a predetermined manners including transmission of said location to said response center; and

Abstract
A vehicle user can request emergency or roadside assistance from a response center by activating a button in the vehicle. The global positioning system is used to continuously store the vehicle location. A cellular telephone network is used to contact a response center and transfer a data string via modem containing information to assist the response center in acting on the request. Prior to attempting dialing 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 center and from the response center to the vehicle.
