Abstract
The navigation system has a display for displaying vehicle service reminders and an input device to permit the driver to define vehicle service intervals. A wheel speed sensor continuously inputs distance data into a CPU. A GPS system receiver continuously inputs date and time data into the CPU. The CPU compares the time and distance data to user defined vehicle service intervals. When the time or distance have exceeded the user defined vehicle service intervals, the CPU generates a vehicle service reminder on the display. The driver can then request the navigation system to guide the driver to an appropriate vehicle service location.
