Route planning methods for navigating an electronic device are disclosed. The method includes the following steps. First, the electronic device generates a planned route according to at least one destination, and performs a navigation process according to the planned route. It is determined whether a route re-planning request has been generated. When the route re-planning request has been generated, a return point is determined from the planned route, wherein the return point corresponds to a current position of the electronic device. A partial route from the current position to the return point is determined. Navigating to the return point is performed according to the partial route and the navigation process proceeds from the return point to the destination according to the planned route.
