Starting Operation
When the vehicle is in ACC mode, the electrical compass unit begins to communicate with the audio unit. Press the engine start/stop button to select the ON mode, the self-test mode begins automatically.
The self-test function checks for the current voltage, non-volatile memory (NVM), and ROM status in the electrical compass unit. If the unit detects a malfunction while in the self-test, it indicates a malfunction by flashing compass information segments (CAL and NW) in the audio display.
The electrical compass unit send the azimuth (direction) information to the audio unit. The electrical compass unit receives the VSP signal from the gauge control module via the audio unit. The azimuth information is fixed while parked.
