84Route setting informationRoute search specificationsYour navigation system sets a route to your destination by apply-ing certain built-in rules to the map data. This section providessome useful information about how a route is set.CAUTIONWhen a route is calculated, the route and voice guidancefor the route are automatically set. Also, for day or timetraffic regulations, only information about traffic regulationsapplicable at the time when the route was calculated isconsidered. One-way streets and street closures may notbe taken into consideration. For example, if a street is openduring the morning only, but you arrive later, it would beagainst the traffic regulations so you cannot drive along theset route. When driving, please follow the actual traffic signs.Also, the system may not know some traffic regulations. The calculated route is one example of the route to yourdestination decided by the navigation system while takingthe type of streets or traffic regulations into account. It is notnecessarily an optimum route. (In some cases, you may notbe able to set the streets you want to take. If you need to takea certain street, set a waypoint on that street.) If the destination is too far, there may be instances where theroute cannot be set. (If you want to set a long-distance routegoing across several areas, set waypoints along the way.) During voice guidance, turns and intersections from thefreeway are announced. However, if you pass intersections,turns, and other guidance points in rapid succession, somemay delay or not be announced. It is possible that guidance may direct you off a freeway andthen back on again. In some cases, the route may require you to travel in theopposite direction to your current heading. In such cases,you are instructed to turn around, so please turn aroundsafely by following the actual traffic rules. In some cases, a route may begin on the opposite side ofa railway or river from your actual current location. If thishappens, drive towards your destination for a while, and tryroute calculation again. When there is a traffic congestion ahead, a detour route maynot be suggested if driving through the traffic congestionwould still be better than taking the detour. There may be instances when the starting point, the way-point and the destination point are not on the highlightedroute. The number of traffic circle exits displayed on the screenmay differ from the actual number of roads.Route highlighting Once set, the route is highlighted in bright color on the map. The immediate vicinity of your starting point and destinationmay not be highlighted, and neither will areas with particu-larly complex road layouts. Consequently, the route mayappear to be cut off on the display, but voice guidance willcontinue.Auto reroute function If you deviate from the set route, the system will re-calculatethe route from that point so that you remain on track to thedestination. This function may not work under certain conditions.Handling and care of discsSome basic precautions are necessary when handling yourdiscs.Built-in drive and care Use only conventional, fully circular discs.
