摘要： A navigation guidance system is provided which gives direction information to a user via their mobile telephone. In one embodiment, the user pre-arranges their trip using a web-based route calculation server. The web-based server prompts the user to provide their mobile telephone number so that updated navigation instructions can be provided to the user as they are travelling towards their destination. In a preferred embodiment, the mobile telephone number and the user's travel plans are transmitted to a second navigation server which transmits a text message to the user's mobile telephone prompting them to call a given number to receive updated navigation instructions to arrive at their chosen destination.
