Problems with Route Guidance Inappropriate route guidance could occur under one or more of the following conditions: • Automatic rerouting may display a route returning to the set stopover if traveling to a destination without passing through a set stopover. • You have not turned onto the road indicated. • Route guidance may not be available when using automatic rerouting for the next right or left turn. • The route prohibits the entry of a vehicle due to a regulation by time or season or any other regulation which may be given. • The route may not be changed when using automatic rerouting. • Some routes may not be searched. • The route to the destination may not be shown if there are new roads, if roads have recently changed, or if certain roads are not listed on the map DVD. See Ordering Map DVDs on page 2-41. • There is no route guidance when turning at an intersection. • Plural names of places may be announced occasionally. If the System Needs Service If the navigation system needs service and the steps listed here have been followed but there are still problems, see your dealer/retailer for assistance. • It may take a long time to operate automatic rerouting during high-speed driving. 2-40
