Navigation System Diagnostic Mode

DVD Mech

Do this procedure only when directed by the factory or other Honda service information (like a service bulletin).

This diagnosis checks the audio-navigation unit internal DVD player mechanism.

- The screen shows DVD Mech version. When the audio-navigation unit can read the version, the screen shows Connection OK. If the version number cannot be read, the screen shows Connection NG.
- Inserting the disc that contains a DVD Mech update program allows you to select Download. Otherwise it is grayed out.
- To update the DVD Mech, you must insert the update disc before selecting this screen. If you insert the update disc when you are on this screen, the Down Load button stays grayed out. If this happens, exit the DVD Mech screen and start the procedure again.





Functional Setup

Select the item you want to check.

- Save User's Memory
- Demo Mode
- All Clear
- Mic Level
- HDD Rec. Deterrent





Save Users Memory

NOTE: If the audio-navigation unit HDD is OK, transfer the HDD to the new audio-navigation unit. Do this procedure only when replacing the HDD (if possible). Since the HDD is NG, it is unlikely you will be able to recover any information.

When replacing the audio-navigation unit, this function allows the technician to transfer the client's personal data to the new audio-navigation unit. The transferred information includes their setup settings and personal addresses. The Save Users memory cannot copy music or photographs that are saved on the old HDD. The dealer inserts a USB device into the USB port, and then selects the Save Users Memory function. The two functions in this diagnostic screen are EXPORT and IMPORT. EXPORT saves the client's data to the USB device, and IMPORT moves the USB device files to the new audio-navigation unit.





This function does not start (the EXPORT and IMPORT buttons are grayed out) until you connect a USB device.

1. Select EXPORT button to move the client's data from the original audio-navigation unit to the USB device. Select Yes on the Export User Data Confirmation screen. The process takes only a couple of seconds. The system stores .DAT files on the USB device.

NOTE: If the EXPORT button is grayed out, check the USB port.





2. After replacing the new audio-navigation unit, allow the system to boot up. Insert the USB device into the USB port and enter the Save Users Memory in the navigation system diagnostic mode.

3. Select the IMPORT button to move the two files stored by the Export process from the USB device to the new audio-navigation unit. Select Yes on the Import User Data Confirmation screen. When the transfer is finished (a few seconds) the system automatically reboots. After the system reboots, remove the USB device from the USB port.

NOTE: If the IMPORT button is grayed out, check if the Model and the Program Flash shown on the Version screen are the same.






Demo Mode

This screen is for factory use only, and should always be set to OFF. Occasionally the 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 a destination when the vehicle is stationary. The Speed Rate changes the speed of the demo mode.






All Clear

The all clear function deletes all ripped music, images, cell phone information, previous destinations, and the phone book from the HDD.

When All Clear is selected, the system restarts after performing the All Clear process. After the restart, a normal start-up process occurs and needs GPS initialization.





If you select Yes, the second confirmation screen appears.





Mic Level

This diagnosis allows you to independently test the microphone and the 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. The microphone can now isolate the driver's voice even when there is noise or other conversations in the vehicle. To properly check the microphones, make sure you are sitting in the driver's seat.

- Press the TALK button on the steering wheel, wait unit you hear a beep, 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 talk indicator shown on the screen does not briefly turn green when you press the TALK button, check the wiring from the steering wheel TALK button to the HandsFreeLink control 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 HandsFreeLink control unit and the audio-navigation unit. If the wires are OK, the microphone must be faulty; replace the microphone located in the roof console Front HFL-ANC/Active Sound Control Microphone Removal / Installation.
- 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 to green, then check the wiring from the steering wheel BACK button to the HandsFreeLink control unit.

NOTE: The Mic level should reach the 6th bar.





HDD Rec. Deterrent

This setting allows you to enable or disable recording CDs to the HDD. Refer to the Owner's Manual for more information about ripping music to the HDD.

NOTE: If the HDD Rec. Deterrent is set to on, and the client tries to rip a CD to the HDD, an error message appears on the screen. Refer to the Navigation Manual.

Deterrent Setting to ON





XM (HIP)

This diagnosis checks the wire connections between the XM (HIP) components.






XM Status

You can check the XM status in this screen. For problems with XM signal reception, refer to the audio section.










B-CAN

This diagnosis checks whether the audio-navigation unit is receiving B-CAN data properly.

B-CAN (Body Controller Area Network) passes information between processors on the network. The B-CAN network uses a communication protocol that transmits data at 125 Kbps.

- This diagnosis must have the engine running.
- If any icon colors red, check for B-CAN DTCs with the HDS.
- The data displayed in the ID boxes is for factory use only.





GPS Information

This screen shows the current status of GPS reception. The circular diagram shows the current location of the GPS satellites (yellow numbers) as they would appear in the sky. The outer circle represents the horizon (0 degrees elevation). The middle and inner circles represents 30 and 60 degrees respectively. The very center of the diagram (90 degrees elevation) is directly overhead. Nearby obstructions, like tall buildings will block satellites in that direction. That is why it is necessary to be in an open area to effectively troubleshoot GPS reception issues. The satellite numbers shown on the diagram correspond to the PRN number in the GPS Details screen. There are always at least 24 active GPS satellites in orbit. Because satellites fail, and have to be removed from service, spares are always parked in orbit, ready to be activated. This is why the PRN (satellite ID number) can be greater than 24.

NOTE: When you use this screen for troubleshooting, park the vehicle outside, away from buildings, tall trees, and high-tension wires for at least 10 minutes with the engine running.

- The Number of Satellites box shows the number of acquired satellites (maximum of 12). It should contain four or more icons. If not, go to GPS icon is white or not shown troubleshooting GPS Icon Is White Or Not Shown.
- The Current Position shows latitude, longitude, and elevation (in feet). If there are less than four satellites, the elevation can be grossly inaccurate.
- The Date/Time field shows the current date, and also GMI time.





NOTE: Pressing the MAP/GUIDE button displays the satellite number on each circle.

GPS Detail

By pressing and holding the MENU button for 2 seconds, a GPS Detail screen appears. This screen displays real time incoming satellite positional data when the vehicle is outside in the open. The information shown on this screen is for factory use.

NOTE: The data shown is an example only.





- The box TS/AS and H Dop (horizontal dilution of precision)/V Dop (vertical dilution of precision) is for factory use.
- The Speed and Direction information is updated in real time when driving.
- The Date/Time Information is the same as in Setup screen 2 Adjust Time Zone/Clock.
- If the 3D icon is shown above the yellow dots, this implies that at least four satellites are available for map positioning, and the GPS indicator on the map screen will be green. See the Global Positioning System detailed explanation in the System Description.
- If the row of data in the table below begins with a yellow dot, the AZI and EL fields can be used to locate each satellite on the circular GPS diagram (see prior screen).

The table of values shown below define the terms at the top of the columns in the GPS detail screen.
