A display interface is located in a vehicle. A is processor in communication with a vehicle sensor and a server. The processor is configured to receive vehicle information and road information, predict a traveling direction of the vehicle based on the vehicle information, and highlight the road information associated with the traveling direction on the display interface. A corresponding vehicle and method is also provided. A user of a navigation map can obtain auxiliary information to drive on the current route from a navigation interface more conveniently during the process of using the navigation map, thus providing the user an improved driving experience. ## Claims ### Claim 1 A navigation system comprising: a display interface located in a vehicle; and a processor, in communication with a vehicle sensor and a server, configured to receive vehicle information and road information, predict a traveling direction of the vehicle based on the vehicle information, and highlight the road information associated with the traveling direction on the display interface. ### Claim 2 (depends on 1) The navigation system of claim 1, wherein the vehicle information includes one or more of: speed information, acceleration information, steering operation, braking operation, vehicle positions, lane confirmations, navigation information, and travel logs; and the road information includes information with respect to traffic signs and/or traffic signals. ### Claim 3 (depends on 2) The navigation system of claim 2, wherein to highlight the road information includes one or more of: to change size, to adjust color, or to adjust a contrast ratio of the road information associated with the traveling direction on the display interface, or to show the road information associated with the traveling direction on the display interface individually. ### Claim 4 (depends on 3) The navigation system of claim 3, wherein when the navigation system is operated in a navigation mode, the processor is configured to: predict the traveling direction based on the vehicle positions and the navigation information; and highlight the traffic signs and/or traffic signals associated with the traveling direction on the display interface. ### Claim 5 (depends on 3) The navigation system of claim 3, wherein when the navigation system is operated in a cruise mode, the processor is configured to: predict the traveling direction based on the vehicle positions and the lane confirmations;
