Abstract
A navigation system for a vehicle includes a vehicle-based telematics system, a vehicle-based global positioning system and a control. The telematics system is operable to receive a user input from a driver of the vehicle and to download directional information from an external service provider to the control in response to the user input and an initial geographic position of the vehicle. The directional information comprises at least two instructions with each of the instructions being coded or associated with or linked to a respective geographic location. The control is operable to provide an output corresponding to each of the instructions in response to a current actual geographic position of the vehicle. The control is operable to provide each instruction only when the then current actual geographic position of the vehicle at least generally corresponds to the particular geographic location associated with the instruction.
