ABSTRACT:
A navigation system includes a driver presence sensor and engine running detection circuitry. When the detection circuitry determines that the engine of the vehicle is not running, the navigation system enters a low power mode. When the presence of the driver is detected, the navigation system begins power up, switching from a low power to a full power operational mode. If the detection circuitry does not determine that the engine is running within a predetermined time period, the navigation system reenters the low power mode. The detection circuitry monitors the vehicle's electrical system and determines that the engine is running when an AC content exceeds a predetermined threshold.
