 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.

This performs additional checks on the communication
bus between navigation CPU and the display. In
addition, the test checks the internal electronic
functions.
If the connection is NG, replace the navigation unit.
 Connection verifies internal communications.
 Version represents the software version for the display.
This diagnostic screen checks the internals of the radio
(AM and FM) and CD player. If NG, replace the
navigation unit. This screen looks for problems with the navigation unit.
When you initiate this diagnostic, the navigation unit
may freeze of delay up to a minute while the diagnostic
runs.
 If V-RAM or D-RAM is NG, then replace the navigation unit.
 If GPS indicates NG (ANT), check the entire GPS antenna wire from the navigation unit to the antenna.
If the wire is crushed or damaged, try a known-good
antenna. If this diagnostic reads OK, then order a new
GPS antenna. If the diagnostic still reads NG (ANT),
replace the navigation unit.
 DVD ROM represents the database version on the DVD. You can also find this information in setup by
selecting System Information.
 Serial No. should be the same as the serial number found on the underside of the navigation unit. You
need this number to obtain the security code from the
Interactive Network system.
 Mem Clear is for factory use, and should never be used unless instructed by the factory. Accidental
selection will erase the client’s personal data, PINS,
and settings. If selected, a popup box appears asking
if you want to clear the memory. If so, select Yes.

sound, and the system outputs a canceling sound from the audio speaker.
AM (Amplitude Modulation)
Amplifier A device that increases the level of a signal by increasing the current or voltage.
Antenna A device used to send or receive electromagnetic waves thr ough the air.
ATA (PC Card) A type of card that has been tested for use in playing WMA, and MP3 music files in the PC Card slot. Sizes of up to 1 GB have been tested.
Audio remote switch The switches on the steering wheel that control the audio system.
Auxiliary jack Allows the customer to use a portable audio device to i nput audio recordings.
Balance A control that changes the relative volume of the left and right channels.
Band A range of frequencies between two definite limits. Bands are assigned by the Federal Communications Commission for specific uses.

labels can curl up and jam the unit.
CD (audio disc) changer CD player that can store and play more than one CD. Two types are available. Some units accept CDs fed into the changer one at a time, and others accept a
magazine (with CDs stacked in a container).
CD player A com ponent designed to play compact disc recordings using a laser optical
pickup. The signal from a CD player usually requires amplification.
Decibels (db)
Distortion Inexact repr oduction of an audio signal caused by playing music at levels the
audio system cannot handle.
Dolby (noise reduction) A processing system developed by Dolby Laboratories that reduces the background noise on recording media. The result is a cleaner playback from the
audio system.

Reception level indication mode
Preperation:
23-193
This diagnostic screen checks the audio unit’s reception level. This level then can be used in the diagnosis of audio
unit reception quality. The reception level is displayed in decibels (dB)
 Pank the vehicle putdoors in an appropriate location for good radio reception.
 Tune to a powerful local FM radio station then write down the radio station number. 1. Enter the reception level indication mode in the self-dia gnostic function. The AM/FM antenna amplifier is on (A.
SEL or TP is not displayed in the audio-HVAC display).
2. Tune to the FM radio station you wrote down preperation using the T UNING knob, and note the decibel level of
that station when you release the button.
3. Press and release the A. SEL button to turn the AM/FM antenna amplifier off (A. SEL or TP is now displayed in the audio-HVAC display).
4. Tune to the FM radio station you wrote down in preperation using the T UNING knob, and note the decibel level of
that station when you release the button.
5. Press and release the A. SEL button to turn the AM/FM antenna amplifier back on (A. SEL or TP is not displayed in the audio-HVAC display.
6. Turn the ignition switch to LOCK (0) or audio unit off to exit the test mode.
7. Compare your results to a known-good, (make sure it is the same year and trim level) in the same location and
direction, and under the same environmental conditions.
