       FIG. 1  is a schematic diagram of a system  100  according to one embodiment. In  FIG. 1 , a system may include a vehicle mounted GPS system  102 , a handheld GPS unit, a mobile telephone with GPS capability, etc., which may include a display  110  which is capable of visually outputting geographic information and/or textual information. The vehicle  108  in which the GPS system  102  may be mounted might be a car, bus, truck, tractor-trailer, sailing vessel, motorboat, tugboat, freighter, aircraft, helicopter, bicycle, motorcycle, scooter, golf cart, etc. In  FIG. 1 , the vehicle  108  is depicted as a car, but this in no way limits the scope of the invention or type of vehicle in which the GPS system  102  may be mounted. 
     The GPS system  102  may be nonremovably coupled to the vehicle  108 . For example, the GPS system may be “built in” to the car, as opposed to a device that is detachable from the vehicle. Thus, a nonremovably coupled system may include or use an in-vehicle display screen that is also used for other things. In another approach, the GPS system  102  may include a GPS navigational device adapted for removable mounting on the vehicle  108 . In more approaches, the GPS system  102  may include a separate, removable antenna and/or a fixed, nonremovable antenna. If the GPS system  102  includes a separate antenna, the antenna may be fixedly or removably coupled to the vehicle  108 , and may be automatically recognized by the GPS system  102  whenever they are placed in electrical communication or within range of each other. 
     The GPS system  102  may generally include a processor for resolving inputs and/or outputs, computations, and/or various functions normally associated with a processor (e.g., microprocessor, application specific integrated circuit (ASIC), field programmable gate array (FPGA), etc.) in a GPS equipped device. Also, the GPS system  102  may include computer usable medium having computer usable program code embodied therewith. The computer usable medium may be any medium known in the art, such as solid state (e.g., flash) memory, RAM, ROM, CD-ROM, DVD-ROM, BLU-RAY, programmable logic, etc. The computer usable code may, when executed, cause the processor to perform certain tasks. The following tasks are in no way meant to limit the functionality of the system, and additional or less tasks may be performed by the processor in any given embodiment. Further embodiments may include ASICs or other hardware to perform any or all of the features proposed herein. In some approaches, an ASIC may be considered a processor, with or without computer usable program code embodied therewith or accessible thereby. 
     In some embodiments, the GPS system  102  may send a request to transmit geographic data from a mobile GPS unit, where mobile GPS device and mobile GPS unit are used interchangeably herein. Any type of mobile GPS unit may be requested to transmit data, including GPS equipped mobile devices like mobile phones  106 , BLACKBERRY devices  104 , PALM devices, APPLE iPHONE devices, laptop computers, tablet computers, personal computers (PCs), GPS navigational devices adapted for removable mounting on a vehicle, etc. 
     In another approach, the mobile GPS unit may initiate the transfer of geographic data to the GPS system  102 . In this approach, the mobile GPS device and the GPS system  102  may be previously linked, linked during the initiation of geographic data transfer, etc. 
     In some preferred embodiments, the communication between the various devices such as a vehicle mounted GPS system  102  and a mobile GPS unit  104 ,  106  may be effected via a wireless link, such as BLUETOOTH, WI-FI, RFID protocols, etc. Of course, the request may also be sent over a hardwired connection, such as a USB connection between devices, docking station, serial connection, IEEE 1394 interface (FIREWIRE), etc. 
     Further, in some embodiments, the GPS system  102  may receive the geographic data from a mobile GPS unit  104 ,  106 . The GPS system  102 , which may comprise a processor, may receive the geographic data through standard wired connections such as USB, FIREWIRE, serial connection, etc., or it may receive the geographic data through a wireless link, such as BLUETOOTH, WI-FI, RFID, etc. 
     In some embodiments, the geographic data may comprise waypoints, destinations, origins, routes, speeds, distances, travel times, favorites such as user-defined locations, etc. Any type of data that may be useful for determining a location and/or calculating travel distances, travel durations, best travel routes, shortest travel routes, fastest travel routes, normal travelling tendencies, etc., may comprise geographic data and may be transmitting to and/or from the mobile GPS unit and the GPS system  102 . In one approach, the geographic data is a physical location in the form of geographical coordinates or any other format that is usable by the receiving device. The type of geographical coordinates is not critical. For example, illustrative types of geographical coordinates includes Cartesian coordinates (e.g., longitudinal and latitudinal coordinates), coordinates used by a mapping system or software, an address, coordinates commonly used in present GPS systems, polar coordinates relative to a base point, etc. 
     In additional embodiments, the GPS system  102  may integrate the received geographic data with previously or coincidently stored data. Previously or coincidently stored data may include present geographic location of the GPS system  102 , time, date, travelling speed, geographic region, surrounding waypoints, etc. 
     In some embodiments, integrating the received geographic data with previously stored data may include choosing only unique geographic data (i.e., geographic data which is different from previously stored geographic data) to receive into the memory of the GPS system  102 , such that after the data is received, the two GPS devices (vehicle mounted GPS system and portable GPS unit) may be synchronized, with the vehicle mounted GPS system having all the latest data stored in its memory. Also, a synchronization technique may be used where only unique geographic data is sent from the mobile GPS unit to the GPS system  102 , thereby reducing communication time and/or costs to accomplish the synchronization. A further synchronization technique may include transferring data both ways between the devices so that each has at least some common data thereon. 
     In more approaches, any data that is synchronized between the devices which is not consistent on one device may be requested again from the other device and/or a new request for the data may be sent to a GPS system supplying the GPS information to the devices, such as GPS satellites, repeating towers, etc. 
     In some embodiments, the integrated geographic data may comprise newly acquired geographic data from the mobile GPS unit. In other embodiments, the integrated geographic data may comprise the newly acquired geographic data and any previously or coincidently stored data, possibly including geographic data and other types of data. 
     In further approaches, the GPS system  102  may simply receive data of any type from the mobile GPS unit. 
     In some approaches, the processor may be caused to use the integrated geographic data to produce a geographic solution. A geographic solution may include a route between two or more locations; a map showing a location, destination, origin, etc.; directions to travel from one location to one or more other locations; etc. Also, in some embodiments, the directions may be turn-by-turn directions of the type normally associated with vehicle mounted GPS systems, which may direct a driver to turn at certain intersections, indicate road names, continue driving for certain distances, what kind of travelling time to expect, etc. 
     In additional approaches, the geographic solution may include estimated travel time, elapsed travel time, average travelling speed, current travelling direction (north, south, east, west, etc.), current travelling speed, remaining travel time, etc. 
     In some embodiments, the processor may be caused to output a geographic solution. Any type of geographic solution may be output, including but not limited to those types described above. In addition, the output of the geographic solution may be visual  110 , verbal or audible  116 , or both. For example, a visual output  110  may show a map  118  including a route between two locations, and a verbal output  116  may indicate turn-by-turn directions  120 , such as approximate times to turn, when to continue straight, when to stop, etc. In another example, a visual output  110  may show a list of directions, and an audible indicator (e.g., a sound, such as a beep, ding, honk, buzz, etc.) may indicate that a change in direction is indicated by the directions. The audible indicator may change frequency, loudness, etc., to indicate the change in direction is closer. 
     Note that several illustrative embodiments described herein discuss transfer of information from a mobile GPS device  104 ,  106  to a GPS system  102  and/or use of such information by a GPS system  102 . Such transfer and/or use may also be reversed, i.e., a mobile GPS device  104 ,  106  may receive and/or use information from a GPS system  102  such as a vehicle-mounted GPS system. Moreover, such transfer and/or use may also be performed between the mobile GPS devices  104 ,  106 , possibly through an interface with the GPS system  102 . 
     Now referring to  FIG. 2 , a method  200  according to one embodiment is shown. As an option, the method  200  may be implemented in the context of the architecture and environment of  FIG. 1 . Of course, however, the method  200  may be carried out in any desired environment. The method  200  is generally performed by a GPS equipped device, such as a vehicle mounted GPS system, but this example is for explanatory purposes only and in no way limits the scope of the invention. 
     With continued reference to  FIG. 2 , in operation  202 , a request is sent to a mobile GPS unit to transmit geographic data. This request may be initiated by a user, by another device, such as a vehicle mounted GPS system, or by any other system capable of producing such a request. For instance, this request may be initiated when a device, such as a vehicle mounted GPS system is powered on, when a car is started, when a certain event happens, after a connection between the devices is established, in response to a request received from the mobile GPS unit, etc. In addition, this request may be transmitted through a wireless link, such as those described above, or may be through a hardwired link, as described above. 
     In some embodiments, the geographic data may be geographic data, coordinates, directions, etc., as described above. 
     In operation  204 , the geographic data from the mobile GPS unit is received. In some embodiments, only unique geographic data (i.e., geographic data which is different from previously stored geographic data) may be received, such that synchronization may take place within the device which has received the geographic data, such as a vehicle mounted GPS system. In more approaches, any data that is synchronized between the devices which is not consistent on one device may be requested again from the other device and/or a new request for the data may be sent to a GPS system supplying the GPS information to the devices, such as GPS satellites, repeating towers, etc. 
     In operation  206 , the received geographic data is integrated with previously stored data. In some embodiments, there may be no previously stored data, thereby allowing the received geographic data to comprise the memory of the device receiving the data, such as a vehicle mounted GPS system. In other embodiments, the device receiving the geographic data may have data previously stored thereon, such as geographic data and other types of data such as current time, temperature, synchronization data (including device information for data transfers, wireless and hardwired transmission protocols, etc.), management data (database format information, file format information, conversion tools, etc.), etc. 
     In operation  208 , the integrated geographic data is used to produce a geographic solution. The geographic solution may include a route between two or more locations; a map showing a location, destination, origin, waypoint, favorite, etc.; directions to travel from one location to another; etc. The map may be generated from data retrieved from a local computer readable medium, from a remote source e.g., via wired or wireless link, etc. 
     Also, in some embodiments, the directions may be turn-by-turn directions of the type normally associated with vehicle mounted GPS systems, which may direct a driver to turn at certain intersections or head in a certain direction, continue driving for certain distances, what kind of travelling time to expect, etc. The directions may also be text based, visually based, audibly based, where a user may select to receive the directions in one or more desired forms. 
     In additional approaches, the geographic solution may include estimated travel time, elapsed travel time, average travelling speed, current travelling direction (north, south, east, west, etc.), current travelling speed, remaining travel time, etc. 
     In operation  210 , the geographic solution is outputted. Any type of geographic solution may be output, including but not limited to those types described above. In addition, the output of the geographic solution may be visual, verbal, or both. For example, a visual output may show a map including a route between two locations, and a verbal output may indicate turn-by-turn directions, such as approximate times to turn, when to continue straight, when to stop, etc. In another example, a visual output may show a list of directions, and an audible indicator (e.g., a sound, such as a beep, ding, honk, buzz, etc.) may indicate that a change in direction is indicated by the directions. The audible indicator may change frequency, loudness, etc., to indicate the change in direction is closer. 
     Now referring to  FIG. 3 , a method  300  according to one embodiment is shown. As an option, the method  300  may be implemented in the context of the architecture and environment of  FIGS. 1-2 . Of course, however, the method  300  may be carried out in any desired environment. The method  300  is generally performed by a GPS equipped device, such as a mobile GPS unit, like a mobile phone, BLACKBERRY, etc., but these examples are for explanatory purposes only and in no way limit the scope of the invention. 
     With continued reference to  FIG. 3 , in optional operation  302 , a request to synchronize data with a vehicle mounted GPS system is received. This request may be initiated by a user, by another device, such as a mobile GPS unit, or by any other system capable of producing such a request. For instance, this request may be initiated when a device, such as a mobile GPS unit is powered on, when a mobile GPS unit is brought within a certain distance of another GPS equipped device, when a certain event happens, etc. In addition, this request may be transmitted through a wireless link, such as those described above, or may be through a hardwired link, as described above. 
     In operation  304 , geographic data is transmitted to a vehicle mounted GPS system. In some embodiments, the geographic data may be waypoints, destinations, origins, routes, speeds, distances, travel times, favorites, etc. Any type of data that may be useful for calculating travel distances, travel durations, best travel routes, shortest travel routes, fastest travel routes, normal travelling tendencies, etc., may comprise geographic data and may be transmitted to and/or from devices, such as a mobile GPS unit and the vehicle mounted GPS system. 
     In operation  306 , a confirmation indicating that the transmission was successful is waited for, whereas if the confirmation is not received before a predetermined time period passes, the geographic data is retransmitted to the vehicle mounted GPS system. The predetermined time period may be any length of time, including several microseconds up to about a minute or longer. In some embodiments, it may take longer to transmit all the geographic data, and therefore longer waiting periods are possible depending on the circumstances of the individual application. 
     Now referring to  FIG. 4 , a method  400  according to one embodiment is shown. As an option, the method  400  may be implemented in the context of the architecture and environment of  FIGS. 1-3 . Of course, however, the method  400  may be carried out in any desired environment. The method  400  is generally performed by a GPS equipped device, such as a mobile GPS unit, like a mobile phone, BLACKBERRY, etc., but these examples are for explanatory purposes only and in no way limit the scope of the invention. 
     With continued reference to  FIG. 4 , in operation  402 , a request to synchronize data with a vehicle mounted GPS system is sent. This request may be initiated by a user, by another device, such as a vehicle mounted GPS system, or by any other system capable of producing such a request. For instance, this request may be initiated when a device, such as a mobile GPS unit is powered on, when a mobile GPS unit is brought within a certain distance of another GPS equipped device, when a certain event happens, etc. In addition, this request may be transmitted through a wireless link, such as those described above, or may be through a hardwired link, as described above. 
     In operation  404 , a confirmation to synchronize geographic data is received from the vehicle mounted GPS system. Any type of geographic data, as described above, may be included in the synchronization. In addition, other types of data that would be helpful in performing tasks by the two GPs equipped devices may be synchronized as well. 
     In operations  406  and  408 , geographic data is communicated between the vehicle mounted GPS system and another device, such as a mobile GPS unit. Once again, additional types of data may be transmitted and/or received in the synchronization, depending on the particular application and circumstances. 
     In operation  410 , a confirmation indicating that the synchronization was successful is waited for, whereas if the confirmation is not received before a predetermined time period passes, the request to synchronize data is resent to the vehicle mounted GPS system. The predetermined time period may be any length of time, including several seconds up to about a minute. In some embodiments, it may take longer to transmit all the geographic data, and therefore longer waiting periods are possible depending on the circumstances of the individual application. 
     Now referring to  FIG. 5 , a method  500  according to one embodiment is shown. As an option, the method  500  may be implemented in the context of the architecture and environment of  FIGS. 1-4 . Of course, however, the method  500  may be carried out in any desired environment. The method  500  is generally performed by a GPS equipped device, such as a vehicle mounted GPS system, like a car navigation system, but this example is for explanatory purposes only and in no way limits the scope of the invention. 
     With continued reference to  FIG. 5 , in operation  502 , geographic data from a mobile GPS unit is received. All of the previous descriptions of geographic data, mobile GPS units, etc., apply to these embodiments. 
     In operation  504 , the received geographic data is used to produce a geographic solution. A geographic solution may be of any of the types previously described. 
     In operation  506 , the geographic solution is output, verbally, visually, or otherwise. In preferred embodiments, the geographic solution may be output both verbally as turn-by-turn directions, and visually as a map or dynamic route. In another example, a visual output may show a list of directions, and an audible indicator (e.g., a sound, such as a beep, ding, honk, buzz, etc.) may indicate that a change in direction is indicated by the directions. The audible indicator may change frequency, loudness, etc., to indicate the change in direction is closer. 
     Now referring to  FIG. 6 , a method  600  according to one embodiment is shown. As an option, the method  600  may be implemented in the context of the architecture and environment of  FIGS. 1-5 . Of course, however, the method  600  may be carried out in any desired environment. 
     With continued reference to  FIG. 6 , in operation  602 , a link is established between a mobile GPS unit and a vehicle mounted GPS system. In some embodiments, the mobile GPS unit may be a mobile phone, BLACKBERRY device, personal GPS unit, another vehicle mounted GPS system in the same or a different vehicle, etc. The vehicle mounted GPS system may be a car navigation system, an airplane navigation system, a nautical navigation system, etc., and may be permanently mounted in the vehicle, or removable, such as a MAGELLAN navigation system, TOM TOM navigation system, GARMIN navigation system, etc.

     In operation  604 , geographic data is transmitted from the mobile GPS unit to the vehicle mounted GPS system. Also, in some embodiments, the vehicle mounted GPS system may transfer and/or synchronize geographic data to the mobile GPS unit. 
     All of the preceding descriptions of mobile GPS units, vehicle mounted GPS systems, geographic data, hardwired and wireless links, etc., apply to this embodiment. 
     In addition, the link may be established automatically by either device each time the device is powered on, each time a device is in range of a wireless connection, each time a hardwired connection is established, each time a certain event occurs, such as passage of time, application started, user initiation, etc. 
     In some embodiments, the mobile GPs unit may wait to receive a confirmation indicating that the transmission was successful, whereas if the confirmation is not received before a predetermined time period passes, the geographic data is retransmitted to the vehicle mounted GPS system. The predetermined time period may be any length of time, including several seconds up to about a minute. In some embodiments, it may take longer to transmit all the geographic data, and therefore longer waiting periods are possible depending on the circumstances of the individual application. Also, an action may terminate the period of time early, such as user input, the device powering down, etc. 
     Now referring to  FIG. 7 , a method  700  according to one embodiment is shown. As an option, the method  700  may be implemented in the context of the architecture and environment of  FIGS. 1-6 .

In addition, other types of data that would be helpful in performing tasks by the two GPs equipped devices may be synchronized as well. 
     In operations  706  and  708 , geographic data is communicated between the vehicle mounted GPS system and another device, such as a mobile GPS unit. Once again, additional types of data may be transmitted and/or received in the synchronization, depending on the particular application and circumstances. 
     In some embodiments, a confirmation indicating that the synchronization was successful may be waited for, whereas if the confirmation is not received before a predetermined time period passes, the request to synchronize data may be resent to the vehicle mounted GPS system.

Additionally, some or all of the code may be printed or otherwise visually displayed on an object (e.g., some or all of the code may be displayed on a card, paper, etc.) 
     While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation. Thus, the breadth and scope of an embodiment should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents. 
     Examples 
     The following examples are for explanatory purposes only, and in no way limit the scope of the invention or the possible embodiments thereof. 
     In one example, the vehicle mounted GPS system may be a navigational unit in an automobile, such as a factory installed unit or an aftermarket unit. The user of the GPS system may have a portable device, such as a mobile phone, which is equipped with GPS functionality, such that geographic data may be stored in the memory of the mobile phone, such as waypoints, destinations, favorites, routes, etc. Any type of geographic data may be useful when this user drives the automobile. Therefore, in some embodiments, the user might be prompted to synchronize the mobile phone when the car is started or the GPS system is powered on. If the user allows the synchronization, the mobile phone could then transmit geographic data to the GPS system, thereby increasing the stored data on the GPS system, and allowing the user to access the geographic data that is on the mobile device through the vehicle mounted GPS system. The GPS system may then use the new geographic data to calculate geographic solutions, such as turn-by-turn directions from the user&#39;s home to a destination, such as a friend&#39;s house or store. 
     In another example, the vehicle mounted GPS system may be on a fishing boat, whereas a user may have a portable GPS device, such as a personal GPS unit. The user may go fishing with a friend and bring along his personal GPS unit, and the fishing trip may be successful prompting the user to want to return to the same location in his own boat sometime in the future. The user could then set a favorite in his personal GPS unit, which could be synchronized with the vehicle mounted GPS system in his fishing boat, causing the vehicle mounted GPS system to now have the favorite fishing spot accessible to direct the user to the same location again to the good fishing area. 
     In yet another example, a user may be on a business trip in a foreign city, and may come across a destination that he may want to return to again when he has more time on his hands. He could store the destination in his GPS equipped mobile phone as a favorite, and then when he returned to the city sometime in the future, driving a GPS equipped rental car for instance, he could synchronize his mobile phone with the navigational system in the rental car, thereby allowing the user to access the favorite destination from the rental car&#39;s navigational system, and may receive turn-by-turn directions on how to return to the desired destination, possibly verbal prompts on when to turn, how far to drive, and which direction to travel. 
     In a further example, a user may have a mobile phone which does not have GPS functionality, but has access to the Internet. This user may download and/or setup a desired location through an Internet mapping service, such as GOOGLE MAPS, YAHOO! MAPS, etc., which the user may want to transfer to a vehicle mounted GPS system, such as one that might be in an automobile. When the user turned on the automobile, the vehicle mounted GPS system could query all devices within range to determine if any geographic data is available. The mobile phone could then transfer one or more saved locations from the mobile phone to the vehicle mounted GPS system, possibly through a wireless BLUETOOTH connection, thus eliminating the need to reprogram the desired locations on the vehicle mounted GPS system, saving time, effort, and ensuring that the proper locations are stored in the vehicle mounted GPS system. The vehicle mounted GPS system could then output, visually as a map and verbally through turn-by-turn directions, the route to travel to arrive at one or more desired locations from the current location as determined by the vehicle mounted GPS system. 
     In a different example, two vehicle mounted GPS systems may have different geographic data stored therein. The vehicle mounted GPS systems may be car navigation systems, either factory installed or aftermarket purchased and installed. The cars may be parked next to each other and use a BLUETOOTH connection to transfer and/or synchronize geographic data between the navigation systems in each car. The two navigation systems also may be synchronized and/or transfer geographic data between each other through a hardwired connection, such that all unique geographic data on each device is transferred to the other device, and vice versa. In this way, a user can ensure that each vehicle has the same geographic data accessible from each car&#39;s navigation system. Similarly, a detachable navigation system may be taken to another vehicle mounted GPS system, and a synchronization and/or transfer of geographic data may be achieved in this fashion. 
     While various embodiments have been described above, it should be understood that they have been presented by way of example only, and not limitation.
