In recent years, vehicle navigation systems have grown in popularity and are now widely available in a variety of forms, including on-board or autonomous systems and off-board or telematics-based systems. In general, autonomous vehicle navigation systems include vehicle-installed units that utilize locally stored navigation information, such as that stored on a CD or DVD, to provide the user with navigation services such as turn-by-turn directions, etc. Telematics-based systems, on the other hand, utilize wireless voice and data technologies to communicate between vehicle-installed hardware and a system back-end like a call center that stores navigation information, such as updated maps, real-time traffic reports, construction information, etc. Telematics-based systems are thus able to provide the user with turn-by-turn directions and other navigation services using up-to-date information.
Each of these two types of vehicle navigation systems can typically provide a user with a detailed navigation route that guides them from a starting point to a selected destination, and can include additional features known to those skilled in the art. In some instances, a user may want to first plan their route using a navigation-related website, and then follow a route generated by their vehicle navigation system. In instances such as this, it can be helpful if the route generated by the website is similar to that generated by the vehicle navigation system so that discrepancies between the two routes are minimized and thereby reduce the possibility of driver confusion.
