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.
