Solar Angle
This screen is used to graphically display the sun's position as determined by GPS. The navigation system uses the sun's angle, along with the sunlight sensor to control the driver/passenger A/C air flow. The heat that must be removed by the A/C unit 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 degrees elevation). The middle circle is 30 degrees, the center circle is 60 degrees, and the very center is directly overhead (90 degrees).
- 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.
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 look like above.
- 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 "Gyro. Sensor Logs ON." Follow the factory procedure for gathering test data, and properly ending the test.
Send GPS Time
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 ('06 model)
This screen is for factory use only, and should always be set to "OFF." Occasionally "DEMO" setting is turned "ON" when vehicles are being used at Auto Shows or similar events. Turning this feature on, allows the navigation system to automatically follow a route to destination when the vehicle is stationary. The "Speed" can change the speed of the demo mode.
Mic Level
This diagnostic allows you to independently test the microphone and the NAVI TALK and BACK buttons. They are used to activate the voice control 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 drivers seat.
- Press the TALK button on the steering wheel, and in a normal voice say "testing." The TALK indicator on the screen should momentarily become green, and the text "Now Recording..." should appear in yellow. In addition, the Mic Level indicator should on the screen does not briefly become 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 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 Cancel indicator on the screen to momentarily become green. If it does not briefly change to green, then check the wiring from the steering wheel BACK button to the navigation unit.
