1. A route planning method for use in a personal navigation device, comprising the steps in order:
- receiving a first input corresponding to a specific region via an input unit of the personal navigation device;
determining a first predefined location located in the specific region;
planning a first route from a first current position of the personal navigation device to the first predefined location;
performing a navigation operation according to the first route, thus navigating to the specific region;
determining whether a latest current position of the personal navigation device is close to the specific region and displaying an alert display mode when the latest current position of the personal navigation device is close to the specific region, wherein the alert display mode comprises displaying an alert message for asking a second input corresponding to a specific location within the specific region, displaying a full view map corresponding to the specific region, glistening a picture of the personal navigation device, or displaying a button for selection, wherein when the button is selected, a picture for inputting the specific location is entered;
planning a second route from a second current position of the personal navigation device to the specific location, wherein the second input is received during the navigation operation corresponding to the first route.

7. A route planning system for use in a personal navigation device, comprising:
-
an input unit receiving a first input corresponding to a specific region; and a processing unit determining a first predefined location located in the specific region, planning a first route from a first current position of the personal navigation device to the first predefined location, performing a navigation operation according to the first route, thus to navigate to the specific region, wherein the processing unit further determines whether a latest current position of the personal navigation device is close to the specific region, and displays an alert display mode when the latest current position of the personal navigation device is close to the specific region; wherein the processing unit displays the alert display mode by displaying an alert message for asking a second input corresponding to a specific location during the navigation operation and plans a second route from a second current position of the personal navigation device to the specific location, displaying a full view map corresponding to the specific region, glistening a picture of the personal navigation device, or displaying a button for selection, wherein when the button is selected, a picture for inputting the specific location is entered, wherein the processing unit further performs a navigation operation according to the second route, thus to navigate to the specific location. - View Dependent Claims (8, 9, 10, 11)
