Claim 16

The method for scheduling vehicle service of claim 12, further including the steps of: measuring elapsed time; defining a time service interval; storing said time service interval; modifying said time service interval; comparing said elapsed time to said time service interval; and generating a vehicle service reminder based upon a comparison of said elapsed time and said time service interval.

Claim 17

The method for scheduling vehicle service of claim 13, further including the step of displaying the difference between said elapsed time and said vehicle service time interval.

Claim 18

The method for scheduling vehicle service of claim 13, further including the steps of: determining the position of a vehicle service location when said distance travelled exceeds said distance service interval; indicating said position of the vehicle relative to said database of roads; determining a route from said database of roads between said position of the vehicle to said vehicle service location; and generating said route to said vehicle service location.

Claim 19

The method for scheduling vehicle service of claim 12 further including the steps of: receiving a time signal from said position-determining device; utilizing said time signal to measure elapsed time; utilizing said time signal to determine the position of the vehicle relative to said database of roads; comparing said elapsed time to a time service interval; and generating a vehicle service reminder based upon a comparison of said elapsed time and said time service interval.

Claim 20

The method for scheduling vehicle service of claim 12, further including the step of displaying the difference between said distance travelled by the vehicle and said vehicle service distance interval.

Claim 21

A vehicle navigation and service reminder system comprising: a vehicle navigation system determining a position of the vehicle relative to a database of roads, said navigation system determining a distance travelled by the vehicle based on the determined position of the vehicle; a user input device for selecting a desired destination relative to said database of roads; a system for determining a route from said database of roads from said determined position of the vehicle to said desired destination a vehicle service reminder generated based upon a comparison of a distance service interval and said distance travelled as determined by said navigation system; and a system for displaying said position of the vehicle, said determined route and said vehicle service reminder.
