Abstract:
1. A navigation system for a vehicle comprising: a vehicle-based telematics system operable to wirelessly communicate between the vehicle and a remote service provider; a vehicle-based global positioning system operable to determine a geographic location of the vehicle; said telematics system being operable to receive a user input from a driver of the vehicle when the vehicle is at an initial geographic location, said user input comprising a destination address; said vehicle-based global positioning system determining the initial geographic location of the vehicle and said telematics system determining a destination geographic location corresponding to said destination address; said remote service provider determining a determined route between said initial geographic location and said destination geographic location; said navigation system further comprising a vehicle-based control; said telematics system being operable to download said directional information from the remote service provider to said vehicle-based control via said vehicle-based telematics system; said downloaded directional information comprising at least two instructions on said determined route between said initial geographic location and said destination geographic location, each of said at least two instructions being coded or associated with or linked to a respective waypoint geographic location determined by said remote service provider to be on said determined route between said initial geographic location and said destination geographic location; said vehicle-based control being operable to generate an information display visible to a driver of the vehicle, said information display corresponding to respective ones of said at least two instructions of said downloaded directional information, said information display being viewable by the driver of the vehicle at or near an interior rearview mirror of the vehicle, said control being operable to provide said information display only when the then current actual geographic location of the vehicle at least generally corresponds to the particular waypoint geographic location associated with said instructions; and said vehicle-based control being operable to automatically generate a change in information displayed in response to the current actual geographic location of the vehicle being inconsistent with said determined route between said initial geographic location and said destination geographic location, said vehicle-based control automatically generating said change in information displayed without further communication with said remote service provider and without further user input.
