 This diagnostic step tests the cables connecting the
navigation components. Ensure that the ignition
switch is in the ON (II) position. When the diagnosis
begins, you hear a bong sound. The system is in a
Detecting mode, and is waiting for all the items in
white to be tested. This includes the voice control
switch (navigation TALK/BACK buttons), and the
microphone. Press the navigation TALK button on the
steering wheel, and in a normal voice, say ‘‘testing’’.
The Talk indicator on the screen should turn green,
and the voice level indicator should move to at least
the 6th bar to pass. Next, press the navigation BACK
button. The Cancel indicator should turn green.
 If all of the communication lines connecting the system components, and the navigation TALK/BACK
buttons/microphone check out OK (all block diagram
items green), then the OK indicator turns green.
 If there is a problem with the system, the faulty system component item turns red, and the screen
shows NG in red. Use the troubleshooting index, and
other diagnostic screens to help locate the problem.
 The indicator on the screen may not change until you cycle the ignition switch. After repairing the affected
cable or system, repeat this diagnostic.
NOTE: Green boxes and green OK indicate that the
communications lines (cables) are intact. This
diagnostic does not necessarily imply that the
individual components are functioning properly. For
instance, the GPS antenna wire may be crushed, but
still show as green. A road test, or other diagnostic
maybenecessarytofindtheproblem.  Select Return to return to the Diagnostic Menu, or the
Exit Diag button to exit.
NOTE: The Mic Level indicator must reach the 6th bar
or greater to pass the test.

PC Card FAQs
QuestionAnswer
23-151
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 on ’07 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 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. 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.
If 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.
