ABSTRACT:
A method and system are provided for secure over-the-air modification of vehicular options by a vehicle user. The system includes a vehicle and a secure server. The vehicle includes receiver circuitry for receiving and demodulating wireless signals and a controller coupled to the receiver. The secure server is accessible by the vehicle user and generates a vehicular option modification package for provision to the vehicle by generating option parameter modification instructions in response to user parameter modification requests from the vehicle owner and generating authentication information in response to unique server authentication information associated with the secure server. The vehicle's receiver demodulates received wireless signals to generate the vehicular option modification package and the vehicle's controller authenticates the vehicular option modification package and, when the vehicular option modification package is authenticated, modifies the vehicular options of the vehicle in response to the parameter modification instructions.
