Solar Angle
This screen is used to graphically display the sun's position as determined by GPS. The Navi 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 degree elevation). The middle circle is 30 degrees, the center circle is 60 degrees, and the very center is directly overhead (90 degrees).
- The "Auto button" should always be on (yellow).
- The "Angle", "Dir", and "Reliability" settings are used by the factory to simulate the sun's position for debugging this function.
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 screen should say, "PC Card is not inserted". The PC card slot door should always be closed.
- However, if the factory provides a PC card and instructs you to insert it into the PC card slot (label side up), and then slide the PC Card slot door shut. If instructed by the factory. Select "Gyro. Sensor Logs ON". Follow the factory procedure for gathering test data, and properly ending the test.
GPS Offset 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).
- "System Time" is the internal time used by the navigation unit to calculate your position on the map. It is also in Greenwich Mean Time (GMT).
- "Display Time" is the time shown on Setup screen 2 "Adjust Time Zone/Clock", and reflects any changes due to daylight savings time or time adjustments entered by the customer.
- Date, Hour, Minute, and "Set" should not be used.
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 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 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 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.
VSP Count
This screen displays the number of pulses per revolution of the tire. This is for factory use only, and should not be changed.
- "Pulse Count Setting" should always be set to "Auto".
- "VSP Count" should always be "4", and should never be adjusted or set to any other value.
H/U Time Send
This screen determines whether to automatically send the navigation time to the audio-HVAC subdisplay unit. The audio-HVAC display panel connector C (10P) passes this information to the audio-HVAC subdisplay unit. The navigation time can be found in the Setup screen 2 "Adjust Time Zone/Clock" setting.
- "H/U Time Send" should always be set to "ON".
NOTE: Touching "Reset" on the Adjust Time Zone/Clock screen automatically resets this diagnostic function to "ON".
Demonstration
This screen is for factory use only, and should always be set to "OFF". Occasionally this 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 a destination when the vehicle is stationary.
