Log Data
This screen allows the factory to select log data to troubleshoot navigation system issues.
- Normally there is no card in the "PC Card Slot," and the PC slot door should always be closed. The screen should appear as shown.
- However, if the factory provides a PC card and instructs you to insert it into the card slot (label side up). If instructed by the factory, select "Logging VP data Logs ON." Follow the factory procedure for gathering test data, and properly ending the test.
GPS Send Tim
This screen is for factory use only. It allows adjustment of the GPS time. This display updates in real time.
- "GPS Time" is the time as received from the GPS satellites. It is in Greenwich Mean Time (GMT).
- Date, Hour, Minute, and "Set" should not be used.
Demo Mode
This screen allows the navigation system to "drive" a route, when the vehicle is stationary. Typical applications include auto shows, and other events. This feature allow visitors to enter a destination, and see the system "drive" to the destination. No speed signal is needed.
- To initiate the mode select "ON"
- Changing the "speed rate" in the ms (milliseconds) is optional, and represents the time between updates of the VP (vehicle position) movement.
- When you increase the rate, the VP slows down,
because it is updated (moved) at a slower rate.
- When you decrease the rate, the VP is faster,
because it is updated (moved) more frequently.
- 1500 ms is VP at its slowest in demo mode.
- 150 ms is VP at its fastest in demo mode (Default).
- At key off, the setting automatically returns to the default of "Off".
Mic Level
This diagnostic allows you to independently test the microphone and the Talk and Back buttons. They are used to activate the voice control and HFL system. The microphone is located near the map light in the roof console. It is directional, and works best with the voice coming from the driver's seat.
- Press the Talk button on the steering wheel, and in a normal voice say "testing". The TALK indicator on the screen should momentarily turn green, and the text "Now Recording..." should appear in yellow. If the mic level indicator on the screen does not briefly turn green, then check the wiring from the steering wheel Talk button to the navigation unit. If there is no "Mic Level" movement when you speak, then you should check the wires running from the microphone in the roof console to the HFL control unit and the navigation unit. If the wires are OK, the microphone must be faulty; replace the roof console.
- Press the Back button on the steering wheel. This should cause the BACK indicator on the screen to momentarily turn green. If it does not briefly turn green, then check the wiring from the steering wheel Back button to the navigation unit.
Solar Angle
This screen graphically displays the sun's position as determined by GPS. The climate control system uses the navigation systems sun angle, along with the sunlight sensor to control the driver/passenger A/C air flow. The heat that the climate control unit removes varies, depending on the angle of the sun entering the vehicle. This screen is for factory use only, and should not be adjusted.
- The screen shows a circular diagram of the sky oriented in the direction that the vehicle is pointing. During daylight hours a red dot is shown, representing the direction and elevation of the sun. The outer circle represents the horizon (0 ° elevation). The middle circle is 30 °, the center circle is 60 °, and the very center is directly overhead (90 °).
- The "manual tuning" button should always be "OFF."
- The "Angle" is the angle that the sun (shown with red "dot") is above the horizon.
- The "vehicle" value represents the angle, clockwise from North, to the direction that the vehicle position (VP) icon is pointing (always points straight up).
- The "direction" value is the angle, measured clockwise from the VP (straight up) to the suns position.
- The reliability ranges from 1 to 3, and represents the accuracy of the Vehicle Position relative to the sun.
