XM (Without AcuraLink)

This diagnosis tests the GA-Net Bus line between the audio-navigation unit and the XM receiver.

If Connection shows NG, the GA-Net Bus line may be failure. Check for hard error codes.






Smart Card

If the remotes are linked to the vehicle, you can check the remote condition on this screen.





HDD

This screen shows the HDD mount error and the temperature.

The screen shows a list of total and free capacities of each partition.

Select the Error History will display the error history that occurred while reading or writing the data to the HDD.

- If HDD Status shows OK, the connection between the HDD pins and the audio-navigation unit are good.
- If HDD Status shows NG*, replace the HDD HDD Removal / Installation.

*: If HDD Status shows NG, the screen does not show the free and total capacities of each partition, however, it shows the temperature.






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 Download button stays grayed out. If this happens, exit the DVD Mech screen and start the procedure again.

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 the IMPORT buttons are grayed out) until you connect a USB device.

1. Select the 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.
