1. A method for providing routing by a navigation device, said method comprising:
- receiving a destination;
calculating a route to the destination accounting for a plurality of modes of transportation;
presenting a visual indication of progress along the calculated route on a display of the navigation device; and
utilizing mass transit schedule information as a proxy for GPS updates to indicate progress along the calculated route, when such mass transit schedule information is available and when GPS signals are unavailable.

Abstract
A navigational aid device is provided that includes a GPS module, a processor, and memory. The device is configured to automatically determine a route to a destination and to account for, in its determination of a route, a plurality of modes of public, private, or both public and private transportation. Some of these configurations may also be configured to recommend a mode or modes of transportation to take to get to a destination, and/or accept user preferences in recommending a route or the mode or modes of transportation to take to get to the destination.

13. A method for providing routing, said method comprising:
-
receiving a destination through an input of a navigation device; determining a current location using a GPS receiver within the device; receiving user preferences defining selected ones of a plurality of modes of transportation, wherein the plurality of modes of transportation includes public and private modes of transportation; receiving user criteria selected from the group consisting of a specific travel time, passing by a specific site, traveling through a scenic area, passing near the most points of interest, a specific arrival time, and combinations thereof; calculating, on a processor of the device, at least one route to the destination considering the user preferences and criteria, wherein the calculated route includes at least one off-road segment, at least one on-road segment, at least one public mode of transportation segments, and at least one private mode of transportation; providing directions, on a display of the device, for following each segment of the route; and monitoring progress along the route using the GPS receiver when GPS signals are available and mass transit schedule information when GPS signals are unavailable.

14. A navigation device comprising:
-
a display; a memory operable to store mass transit schedule information; a location determining component operable to determine a current geographic location of the navigation device; and a processor coupled with the location determining component, the memory, and the display, the processor operable to; access the memory to acquire the mass transit schedule information, calculate a route to a destination accounting for a plurality of modes of transportation, control the display to present a visual indication of progress along the calculated route based on the current geographic location of the navigation device determined by the location determining component, and control the display to present a visual indication of progress along the calculated route based on the stored mass transit schedule information when the location determining component is unable to determine the current geographic location of the navigation device. - View Dependent Claims (15, 16, 17, 18)
