CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a Continuation Application of U.S. patent application Ser. No. 13/570,868, filed Aug. 9, 2012, which is a Divisional Application of U.S. patent application Ser. No. 10/952,195, filed Sep. 28, 2004, the entirety of which is incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to the field of location-based services. More particularly, the present invention relates to the interaction of location based services and personal information management applications. 
     BACKGROUND OF THE INVENTION 
     Location-based services and location-aware applications are becoming increasingly popular in the area of mobile devices such as cellular telephones. In particular, global systems for mobile communication and code division multiple access (CDMA) have become more accessible and popular with the general public in recent years. Currently, it is possible to use Bluetooth global positioning systems (GPS) with several cellular telephones, and a number of third party application developers are also currently developing applications in this area. 
     In addition to the above, a number of applications are available for aiding users in navigation and route planning. These applications use devices containing global positioning&#39; systems to define the exact location of a mobile device. Although these systems can be quite useful, the usage of location information needs to be easy and convenient for the user in order for the average consumer to become comfortable taking full advantage of the technology. For example, when a user opens contact information for a person or a location, there needs to be a simple and straightforward system for the user to initiate the navigation process (including the accessing of digital map content) towards the particular contact. Currently, however, to complete the navigation process, the user must write down or copy the location information of the contact, initiate the navigation application, and enter the address manually before navigation could begin. Additionally, if the user begins with the navigation program, the user must manually enter the desired address before navigation is possible. 
     Furthermore, currently there is virtually no existing interaction between navigation applications and personal information management and connectivity applications. As a result, a user is required to first save the received landmark to a database, start the navigation application, and then locate the saved landmark from the database before navigation can be initiated. 
     SUMMARY OF THE INVENTION 
     The present invention addresses the above problems by providing a system wherein navigation applications are able to quickly and easily interact with personal information management and connectivity applications. The present invention permits a user to seamlessly move from finding a contact to entering a navigation application and vice versa without the difficulties described above. The system and method of the present invention therefore eliminate the need for the user to take multiple steps to initiate the navigation process, as well as eliminating the need to manually save and transfer contact information to a navigation program. These benefits greatly reduce the complexity involved in using such programs, providing improved access to such programs by a wide variety of end users. According to the principles of the present invention, a system and method is introduced for enabling the fluent interaction between connectivity and personal information management applications and navigation applications (including map content programs). The user of an electronic device is capable of launching a navigation application straight from a personal information management program. In other words, the user can start to navigate towards a currently highlighted contact. This principle also works in reverse, so that there is an access mechanism from the navigation application to contact information, so that the user does not have to manually enter an address before navigation is possible. Instead, the user can launch the personal information management program search the correct contact from there. Additionally, when a user receives location information (e.g. landmarks) from different sources, the user can quickly and easily start navigation straight from an inbox where received messages are stored. 
     These and other objects, advantages and features of the invention, together with the organization and manner of operation thereof, will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, wherein like elements have like numerals throughout the several drawings described below.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention comprises a system and method for automatically associating navigation, personal information management, and connectivity applications to provide a simple method for initiating navigation functions in an electronic device.  FIG. 1  discloses a generic electronic device at  100 . The electronic device  100  can take a variety of forms, including, but not limited to, a portable telephone, a personal digital assistant, a small personal computer, or other products. The electronic device includes a processor  120  for processing information, as well as a memory unit  130  for storing the programs necessary for implementing the present invention. The processor  120  and the memory unit  130  are either directly or indirectly operatively connected to each other so that the processor  120  can process the programs stored in the memory unit  130 . The electronic device  100  also includes a display  180 , which can be used to exhibit graphics, alphanumeric characters, as well as computer icons  185  and/or options within drop-down menus  190  as is discussed hereinafter. 
     The memory unit  130  includes a connectivity program  140 , a personal information management program  150  and a navigation program  160 , all of which are operatively connected to each other to permit the interaction of the various programs. The connectivity program  140  permits the electronic device  100  to receive information from a remote location  110  through the use of a data communication link  170 . The navigation program  160  is used to aid the user in tracking and directing the user to the remote location  110  once the remote location  110  has been identified. The personal information management program  150  can take a variety of forms. For example, the personal information management program  150  can include a system for managing a person&#39;s personal contacts, including protocols for a contact&#39;s electronic devices. The personal information management program  150  can also include a personal messaging system, such as an electronic mail system. All of the programming necessary to implement the present invention can be stored as computer program code within the memory unit  130 . 
     According to one embodiment of the invention, the navigation process is initiated as follows. As shown in  FIG. 2 , the process begins at step  200  when the user opens a personal information management program  150 , such as “Contacts” application. Alternatively, contact information could be stored inside a messaging system, such as an electronic mail system. At step  210 , the user selects the desired contact, with location information included therein. At step  220 , the user selects a “start navigation” option. This option can be implemented in a wide variety of manners, including, but not limited to, having an icon  185  on the display inside the personal information management program  150 , including an option in a drop-down menu  190 , or other systems. At step  230 , the navigation program  160  is automatically opened by the device and, at step  240 , the navigation process for directing the user to the selected location is opened and initiated. In this situation, the navigation program  160  is started straight from the contact information inside the personal information management program  150 , requiring virtually no effort from the user. 
     A second embodiment of the invention is depicted in  FIG. 3 . At step  300 , the user opens the navigation program  160 . At step  310 , the user selects an option for the destination to be selected from the personal information management program  150 . This option can also be implemented via an icon  185  on the display  180 , through a drop-down menu, or other mechanisms known to those in the art. At step  320 , the personal information management program  150  automatically opens. At step  330 , the user selects the appropriate contact, with location information located therein. At step  340 , the navigation program  160  retrieves the location information and the navigation process is initiated. 
     The present invention also permits the substantially simultaneous interaction between the navigation program  160  and the personal information management program  150  while in transit. This system is depicted in  FIG. 4 . At step  400  in  FIG. 4 , the process begins with the user continuously using the navigation program  160  for street navigation, for example navigating streets in the center of a large city. At step  410 , the user comes into the range of defined location information (within 500 meters of the landmark, for example) and obtains an indication relating to that location, which is further attached to contact information stored in the personal information management program  150  of the user&#39; mobile device. At step  420 , the indication contains the portion of the information stored to Contacts, and the precise location information is highlighted on the map of navigation program  160 . At step  430 , the user is able to visit the location, which may have particular meaning for the user since it was already saved to the contacts of his or her mobile device. 
     Furthermore, the present application allows a user to receive location information and immediately use it for navigation purposes. This process is depicted in  FIG. 5 . At step  500  of  FIG. 5 , the user&#39;s mobile device receives location (or landmark) information through the data communication link  170  over one of a wide variety of systems, including, but not limited to, Bluetooth, a multimedia messaging service, an infrared data association, or a hypertext transfer protocol, using the connectivity program  140 . At step  510 , the user observes that the landmark information has been received. At step  520 , the user selects a “start navigation” option, which can be in the form of an icon  185 , an option in a drop-down menu  190 , or another form. At step  530 , the navigation program  160  automatically opens, and navigation towards the location of the landmark is begun. 
     Implementation of the present invention results in a number of distinct advantages over conventional systems having completely independent navigation and personal information management programs  150 . The present invention makes it is easier for a user of a mobile device to use location information for navigation. When location information is attached to existing applications, it is easier for manufacturers to introduce the new technology on a wide scale without requiring substantial learning by the end users. 
     While preferred embodiments have been shown and described herein, it should be understood that changes and modifications can be made to the invention without departing from the invention in its broader aspects. For example, but without limitation, contact information could be obtained from a wide variety of personal information management programs  150 , including, but not limited to, messaging systems, address books, and other applications. Additionally many of the steps described above could be combined and/or modified in various embodiments of the invention. Various features of the invention are defined in the following Claims.
