Another embodiment of the present invention provides a navigation system suitable for an electronic device, including a processing unit and a receiving unit. The processing unit generates a first planned path according to at least a first destination, wherein the electronic device performs a navigation according to the first planned path. The receiving unit receives a message including an identification code and information of a second destination. The electronic device determines whether to perform a path re-planning according to the identification code, and when deciding to perform the path re-planning, generates a second planning path according to the second destination, and navigates with the second planned path. Another embodiment of the present invention provides a navigation method suitable for an electronic device, including the following steps. First, the electronic device generates a first planned path according to at least a first purpose: MIC-2007-350/0506-A41594-TW/Final 201009302, and the electronic device performs a navigation according to the first planned path. Next, a message is received, the message including an identification code and information of a second destination. Based on the identification code, the sub-device determines whether to perform a path re-planning. When it is decided to perform the path re-planning, the electronic device generates a second planned path according to the second item's location and navigates with the second planned path: path.

In this embodiment, the identification code is to send the message. The electronic device receives the above message, and the electronic device can receive the message through the signal receiving unit 130. Similarly, in step S350, the message is checked. Whether the identification code is a special number. At this time, the electronic device compares whether the identification code in the message is equal to the specific number, and if yes, executing steps S360-S380 to start the automatic navigation program; if not, executing steps S400-S430 The manual navigation program is started. ® In step S360, a time period is started, the content of the message is automatically displayed, and the user is prompted whether to cancel the re-route planning. The user can set a time period, for example, 30 seconds or 1 minute, the timing unit 160. A time period of one 30 seconds or one minute will be started according to the set time period. At this time, the electronic device displays the received message through the display unit 120. The content, such as displaying "new destination is XX", and prompting the user whether to cancel the re-route planning. Under the preset situation, when the timing period ends, the electronic device will automatically start the new path planning procedure, automatically based on a second destination in the message, re-arranging a second planning path (step S370), and changing to navigation according to the second planning path, navigating to the second destination (step S380). Suppose the user does not want to change to The new destination (ie, the second destination) can be used to input a request for canceling the re-route planning through the user interface before the end of the time period, for example, pressing a [Cancel] button in the user interface to request the electronic device Ignore this message and stop re-routing. If the ID in the message is not equal to the specific number (No in step S350), it means that the message is not from the identified user, so the step is executed: MIC-2007-350/0506- A41594-TW/Final 11 201009302 S400-S43G, start the manual navigation program.

Then, the electronic device displays the content of the received message through the display unit 12 and does not ask the user whether to re-route. Next, it is determined in step S420' whether a request for re-path planning is received. If no, the process ends. If the user wants to re-route the process (step S42 is OK), the user interface input-re-route planning requirement, such as pressing a [Re-path planning] button in the user interface, to request the electronic device. Re-path planning. Then, in step S43, the electronic device starts the re-path planning process, re-plans a second planning path according to the second destination in the message, and changes to navigate according to the second planning path, and navigates to the second destination ( Step S380). Then, in step S390, it is continuously determined whether other communication is received. Assuming that no other messages have been received before the end of the navigation (No in step 8390), navigation is based on the new second planned path. If the second destination is reached, the navigation ends. It is assumed that other users (e.g., the leader) are ready to change the destination to the third destination again. Thus, a message including the identification code and a third destination is transmitted again to the electronic device. At this time, step S350 is repeated to check again whether the identification code in the message is a specific number. According to the check result, step S360-S380 is selected to start the automatic navigation program: MIC-2007-350/〇5〇6-A41594-TW/Final 12 201009302 or step S400-S430 is executed to start the manual navigation program, and the destination is Change to the third destination. Therefore, even if the destination is changed multiple times, the electronic device can automatically navigate the user to the destination and according to the ': destination in the message', re-plan the appropriate path, and in the process: the latter can hardly operate manually. , greatly increased the convenience of using .3⁄4. For example, in an embodiment, the assumption that the leader P1 has the identification code "1234567" is intended to be collected at a first destination A. A user P2 prepares to navigate through the electronic device 'targeting the first destination A, and first sets the specific number to be the identification code of the leader P1, 丨 234567". A link between the leader P1 and the user P2 is available. A message of a specific format (such as a newsletter) is communicated. On the way, it is assumed that the leader P1 wants to change the collection place to the second destination B, and then sends a message including the identifier "1234567" and the coordinates of the second destination B to the user. The electronic device of P2. After the user of P2 receives the message, because the identification code "1234567" is the set specific number, φ, the re-route planning process is automatically executed, according to the second destination B in the message. Planning a second planning path and changing to navigation according to the second planning path 'Navigate to the second destination B. Then, before reaching the second destination B, assume that the leader pi wants to change the meeting place to the third destination again C, then sends an electronic device including the identifier "丨 234567" and the coordinates of the third destination C to the user P2. Similarly, the user P2's electricity After the sub-device receives this message, since the identification horse "1234567" is the set specific number, the re-path planning procedure is automatically executed, and a third planning path is re-planned according to the second destination c in the message: MlC- 2007-350/0506-A41594-TW/Final 13 201009302 And change == three rules __ navigation, guide &, u, according to the specific format of the information within the date of the guide, the navigation and routing rules , the electronic device will check: code), :; ^ ^ special features = capacity (for example, with the number to make the pro-Saki revisit, no need for the method of invention I or a specific type or part thereof, can be in the form Included in physical media, such as floppy disks, CDs, hard drives, or any other machine readable (such as computer readable) storage media, where:: code is loaded by the machine, such as a computer, and executed The machine becomes a device for use in the present invention.
