    摘要: The system and method may provide directions to the user of an electronic signal such as a radio or television broadcast. The directions guide the user from a current location to a destination associated with the electronic signal by accessing an address embedded within, or transmitted in conjunction with, the electronic signal. The address provides an indication to an online information provider an/or a database within which a listing of locations for a destination are provided. By comparing the various locations of the destination against the current location of the user, determined using Global Positioning System (GPS) data, the system is able to determine which location of the destination is closest and to provide appropriate directions. Maps and various other directional tools, including verbal directions and visual directions, may be generated. Reverse directions may also be generated from a destination to other predetermined way-points such as home, office or starting point.
