One versions of the system makes use of existing components of a wireless telephone system, for example, by using the input and output capabilities of a telephone handset. Another version is a portable system that includes multiple switches for initiating access to a remote server in one of a number of operating modes. For instance the system has switches for initiating traffic information, roadside assistance, personal information, or emergency modes. The system includes a positioning system for generating position data related to a geographic location of the system, and a wireless communication device. The system also includes an audio output device, such as a speaker for presenting the received information. The system can also include a storage for a unique identification of the information system. This identification is passed to the remote server through the wireless communication device. Another version of the system provides both autonomous and client-server based navigation services in which a removable database supports route planning in a limited area and a remote server supports route planning outside that area.
