PC Card FAQs
QuestionAnswer
23-317
Wheredowebuytheflashmemoryor
adaptors, and what do we ask for?You need a PCMCIA type II adaptor and a flash memory chip. You can
purchase them at a computer, or office supply store. The card is the
same size and shape as the PC card in the HDS. Adaptors that accept
multiple flash types are not recommended.
What memory flash chips will work
with what adaptors? The flash memory devices that have been tested include Compact Flash
(CF), and ATA style (like the card in the HDS). Other card types and flash
memory chips may work, but have not been tested.
What capacity card do I need for this
function? A memory chip with capacity of 64 MB to 2 GB will work. The two files
moved to the PC card during export are less than a Megabyte in size.
Should the dealer have a dedicated PC
card for the Export and Import
navigation function? Yes, treat the PC card as a dedicated special tool that you can use any
time you need to transfer the navigation personal files to a new
navigation unit or ’09 and later vehicles.
What device can I use to maintain the
PC card, and delete files? Any computer store sells USB style card readers that accept the PC card,
and allow you to do file maintenance on your PC card. Most laptops will
also accept the PC card.
Can we move the client’s data to
different models? No, the files are model specific and will only load into a navigation unit
with the same part number.
Can we move the client’s data to the
same vehicle with a different software
version (like moving from version 4.41
to version 4.51)? The client’s files can only be transferred to a new navigation unit, if the
Model and the Program Flash shown on the Version screen are the same.
Files cannot be transferred to the different model and different versions.
Will other files on the PC card like
images or music files prevent the
Export/Import function from working? No, the system simply adds two small files that are recognized by the
new navigation unit when performing the import function. However, it
the PC card is full, the Export function won’t work correctly.
Do I have to delete the files on the PC
card after each transfer of the
personal data? After the transfer of personal data to the new navigation unit, the files
remain on the PC card. Since this is confidential information, Acura
recommends deleting these files after the transfer use. Please note that
each time you export navigation files of the same model and version, the
files are overwritten. Over time the PC card accumulates two files for
each version of the 8 or so Acura navigation models.
It the memory card needs formatting,
what format should I use? It is unlikely that the PC card will ever need formatting, however, if it
does, use the FAT (file allocation table) file system.
I can’t enter the navigation diagnostic
mode to do the Export/Import function.
How can I transfer the personal data? Some internal navigation unit ECU failures may make it impossible to
use the Export/Import function.

NOTE:
 Check the vehicle battery condition first.
 Before you troubleshoot, make sure to follow the general troubleshooting information (see page
23-266).
 This code sets when the internal temperature of the navigation unit ECU rises above 70 °C (158 °F). The
unit is designed to shut down to protect the
navigation unit ECU. This could be caused by an
inoperative navigation unit ECU fan or if the
passenger’s compartment temperature exceeds the
maximum. Do the troubleshooting when the unit is
within the allowable temperature range.
1. Check that the temperature is below 70 °C (158 °F) in the passenger’s compartment.
2. Clear the hard error code (see page 23-274).
3. Turn the ignition switch to LOCK (0), and then back to ON (II).
4. Check for the hard error code (see page 23-273).
Replace the navigation unit (see page 23-355).
Intermittent failure, the system is OK at this
time. If the unit repeatedly comes back with the
DTC, replace the navigation unit. NOTE:
 Check the vehicle battery condition first.
 Before you troubleshoot, make sure to follow the general troubleshooting information (see page
23-266).
 This code sets when the internal temperature of the navigation unit ECU falls below 20 °C ( 4 °F). The
unit is designed to shut down to protect the
navigation unit ECU. This is usually caused by very
cold exterior temperatures. Do the troubleshooting
when the unit is within the allowable temperature
range.
1. Check that the temperature is above 20 °C ( 4 °F) in the passenger’s compartment.
2. Clear the hard error code (see page 23-274).
3. Turn the ignition switch to LOCK (0), and then back to ON (II).
4. Check for the hard error code (see page 23-273).
Replace the navigation unit (see page 23-355).
Intermittent failure, the system is OK at this
time.

 DTC 2703 can be stored when the ignition switch is at ACCESSORY (I). With the ignition switch is in
ACCESSORY (I), the climate control unit is turned off
and the navigation unit loses communication and
stores DTCs. Therefore, there is a possibility that the
system is normal even DTC 2703 is stored. Check
system links (see page 23-297) with the engine
running, and if it shows normal, the system is OK at
this time. If not, do this troubleshooting.

Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Confirm the correct DVD color and version is installed in the navigation unit (see page 23-270).
 Refer to General Troubleshooting for a list of common DVD screen error messages and the
probable causes (see page 23-319).
 Check any official Honda service website for more service information about the navigation system.
 Go into the Diagnostic mode and use the ECU Info diagnostic (see page 23-305) to check the status of the
DVD cover.
 Inspect the navigation DVD for scratches or damage.
 The following troubleshooting is for the error message shown on the error messages table
(see page 23-319).
1. Check the DVD-ROM reading surface for scratches and finger prints.
Clean or replace the DVD-ROM (see page
23-270).
If the problem occurs occasionally when the
system is cold, this is normal. If the problem occurs
frequently when driving, replace the navigation
unit (see page 23-355). NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
 Check for and resolve all CAN DTCs before troubleshooting the navigation system.
 If the Hard Error Code stored, check the Hard Error Code troubleshooting first.
 Before troubleshooting, make sure the anti-theft codes for the navigation system.
 After troubleshooting, enter the anti-theft codes for the navigation system.
 Verify that the correct navigation unit is installed for this model. Go into the Diagnostic mode, and use
Version (see page 23-316).
 Make sure that the correct DVD color and version are installed.
 Check any official Honda service website for more service information about the navigation system.
1. Connect the HDS to the DLC. Check for B-CAN or F-CAN DTCs in the data list.
Troubleshoot and repair all CAN related
DTCs, and then retest.
Go to step 2.

5. Substitute a known-good climate control unit. Reconnect all connectors, and retest.
Replace the original climate control unit
(see page 21-75).
Replace the navigation unit (see page 23-355). 1. When a navigation unit is powered up for the first
time at the factory, the factory diagnosis screen (In
Line Diag) appears. Normally the factory performs
the steps necessary to verify proper operation, and
terminate the factory diagnostic. Until the proper
confirmation sequence is performed, the screen
will appear every time the vehicle is started.
2. Follow the steps to prevent the screen from showingupinthefuture:
 Hold down the buttons (Menu, Map/Guide, and Cancel) for about 5 seconds. The Select
Diagnosis Items screen appears.
 Hold down the Map/Guide button for 5 10 seconds. A screen with a Complete button,
appears.
 Touch Complete, and then the Return button (the system may re-boot).
 Restart the vehicle, and confirm normal operation by completing the PDI of the
navigation system Service Bulletin.

 The Navigation System Diagnosis and Core Return From is available online, under Job aids, and can be
printed out for recording this information. This
information will help the reman facility determine
what caused the failure.
 Check the connectors for poor connections or loose terminals.
 Before troubleshooting, make sure you have the anti- theft codes for the navigation system.
