The navigation system consists of the following components:
- a global positioning system (GPS) antenna
- a navigation system display module
The navigation system also receives input signals from the following components:
- The reversing lamp switch
- The anti-lock brake system (ABS) module
Reversing lamp switch
The reversing lamp switch input allows the navigation system display module to determine the vehicle's forward or rearward direction.
ABS module
The ABS module provides information to the navigation system display module to allow the system to determine distance covered. The input is generated from the rear ABS wheel sensors.
