1. A navigation method, comprising:
- receiving a destination by a navigation device;
calculating a route from a first location to a waypoint by the navigation device, the waypoint being a location proximate to the destination; and
providing detailed travel directions via a non-GPS network from the waypoint to the destination by the navigation device so that the navigation device provides complete directions from the first location to the destination in response to the detailed travel directions from the waypoint to the destination being available, wherein the detailed travel directions comprise landmarks or visual cues to define a path for guidance from the waypoint to the destination, the detailed travel directions being provided and customized by an entity affiliated with the destination; and
determining a distance of the path from the waypoint to the destination; and
one of;
rejecting the detailed travel directions in response to the distance of the path exceeding a predetermined threshold; and
ranking the detailed travel directions as unfavorable in response to the distance of the path exceeding the predetermined threshold;
wherein the method further comprises;
determining the distance of the path defined by the detailed travel directions by the navigation device; and
providing a safeguard that the detailed travel directions are bogus in response to the distance from the waypoint to the destination exceeding the predetermined threshold.

1. A navigation method, comprising:
-
receiving a destination by a navigation device; calculating a route from a first location to a waypoint by the navigation device, the waypoint being a location proximate to the destination; and providing detailed travel directions via a non-GPS network from the waypoint to the destination by the navigation device so that the navigation device provides complete directions from the first location to the destination in response to the detailed travel directions from the waypoint to the destination being available, wherein the detailed travel directions comprise landmarks or visual cues to define a path for guidance from the waypoint to the destination, the detailed travel directions being provided and customized by an entity affiliated with the destination; and determining a distance of the path from the waypoint to the destination; and
one of;rejecting the detailed travel directions in response to the distance of the path exceeding a predetermined threshold; and ranking the detailed travel directions as unfavorable in response to the distance of the path exceeding the predetermined threshold;
wherein the method further comprises;determining the distance of the path defined by the detailed travel directions by the navigation device; and providing a safeguard that the detailed travel directions are bogus in response to the distance from the waypoint to the destination exceeding the predetermined threshold. - View Dependent Claims (4, 5, 6, 7, 8)

2. A navigation service executed by a processor, comprising:
-
at least one set of detailed travel directions from at least one waypoint to a destination provided from a non-GPS source, wherein the at least one waypoint comprises a location proximate to the destination, and wherein the at least one set of detailed travel directions are provided and customized by an entity affiliated with the destination and comprises; a list of multiple sets of detailed directions sorted or ranked by at least one predetermined criteria; a set of landmarks or visual cues associated with each set of detailed directions to define a path for guidance from the waypoint to the destination; a set of visual cues available in response to passing the destination; and a set of recovery directions available in response to passing the destination; and wherein a distance of the path from the waypoint to the destination is determined; and
one of;the detailed travel directions are rejected in response to the distance of the path exceeding a predetermined threshold; and the detailed travel directions are ranked as unfavorable in response to the distance of the path exceeding the predetermined threshold;
whereinthe distance of the path defined by the detailed travel directions by the navigation device is determined; and a safeguard that the detailed travel directions are bogus is provided in response to the distance from the waypoint to the destination exceeding the predetermined threshold. - View Dependent Claims (9, 10)
