A system for controlling the access of services from a service provider to a client terminal provides capabilities for the user to change and modify the desired services and have the modified access information communicated to the client terminal or navigation device. The system provides a wireless connection between the client terminal and the server by way of a communications network. The server at the service provider may allow a user to modify the configuration data relating to the access rights of the client terminal. The modified configuration data may be stored on the server and wirelessly transmitted to the client terminal and stored on the client terminal. The modified configuration data may provide access to the services provided by a second service provider allowing the navigation device to access the services that are available on the second service provider as well as those available on the first service provider.
