Abstract
A method of generating a suggested navigation route with a navigation device includes storing in a memory of the navigation device a map database containing names and locations of roads in a road network and off-road trail data containing locations of at least one off-road trail provided by a user of the navigation device, and merging off-road segments of the off-road trail with the roads of the road network to create a combined map database containing off-road segments and road segments. The method further includes receiving a request from the user for generating navigation directions to a destination location input by the user, generating the suggested navigation route using data stored in the combined map database, the suggested navigation route containing a combination of off-road segments and road segments, and providing navigation assistance to the user for guiding the user along the suggested navigation route.
