Abstract
A navigation system determines a route between a first location on a road network and a second location in a facility off of the road network. The system composes individual guidance messages for travel along a portion of the route on the road network. A pre-composed set of guidance instructions for travel in the facility along a portion of the route off of the road network are obtained from a geographic database associated with the navigation system.
