Abstract
A navigation system for a vehicle enables an operator to know a calculated optimal path from a starting point to a destination before departure. After the optimal path is calculated, a preview function allows the operator to sequentially view the calculated optimal path either prior to departure or at any point along the optimal path. A cancel function allows the operator to cancel a displayed portion of the optimal path and to request calculation and display of an alternate optimal path which does not employ the canceled portion of the original optimal path.
