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
changes the speed of the demo mode. This diagnostic allows you to independently test the
microphone and the navigation 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. It is directional, and works only with
the voice coming from the driver’s seat.
 Press the navigation 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, check the wiring from the steering wheel
navigation TALK button to the navigation 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 navigation unit. If the wires are OK, the
microphone must be faulty; replace the microphone
located in roof console (see page 23-358).
 PressthenavigationBACKbuttononthesteering wheel. This should cause the Cancel indicator on the
screen to momentarily turn green. If it does not
briefly turn green, check the wiring from the steering
wheel navigation BACK button to the navigation unit.

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 sate llite
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
three or more icons. If not troubleshoot for GPS icon
is white or not shown (see page 23-341).
 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 a time that includes daylight savings and other
offsets entered by the customer in Setup screen 2
Adjust Time Zone/Clock.
NOTE: Pressing the map/guide button displays the
satellite number on each circle.

This diagnostic checks the yaw rate sensor in the
navigation unit. This device detects when the vehicle
turns, and repositions the vehicle position icon on the
map screen. For more detailed information, see the yaw
rate sensor theory of operation under System
Description (see page 23-283).
 Sensor indicates the voltage output from the yaw rate sensor. It should indicate about 2.500 V when the
vehicle is stopped.
 Offset is the reference voltage or standard within the yaw rate sensor. It also should indicate about 2.500 V
when the vehicle is stopped.
 A sensor output voltage LOWER than the Offset voltage indicates that the vehicle is turning to the
right.
A sensor output voltage HIGHER than the Offset
voltage indicates that the vehicle is turning to the left.
 The yaw rate offset, and sensor should both indicate about 2.500 V when the vehicle is stopped. If either
reads zero, or 5.000 V, replace the navigation unit.
 The yaw rate offset and sensor should be within / 0.01 V of each other when the vehicle is stopped.
The sensor value should change relative to the offset
as the vehicle turns while driving. If not, replace the
navigation unit.

become more accurate.
 The settings CCW Cal Factor, CW Cal Factor, and Set are for factory use only. THIS SHOULD NEVER BE
ADJUSTED.
 For detailed analysis of the yaw rate select tuning.

This diagnostic allows you to graphically display
problems with the yaw rate sensor.
 The ANG-Disp value accumulates any differences between the offset and sensor voltages (see Yaw
Rate diagnostic). When the sensor functions properly,
the random changes in these two voltages generally
cancels out, so the value is 0. However if one voltage
is consistently higher than the other, then the ANG-
Disp value accumulates the constant change.
 The Reset button temporarily clears the angular accumulation (ANG-Disp), and clears the display dots.
 Do not touch the CCW, CW, or Set buttons. These are used for factory setup only.
Two tests are explained below. For large problems with
the sensor values, the stationary test usually confirms
whether the sensor is defective. For yaw rate issues
related to driving, do the road test described below. 1. Stationary test: If the VP icon spins in place and the ANG-Disp value slowly increases or decreases in
value, the yaw rate sensor is defective. Replace the
navigation unit.
2. Road test: Drive the vehicle on a very straight road. Enter the diagnostic mode, select Yaw rate, and
touch the Tuning button. While driving down a
straight road, the white dots should trace a straight
line across the screen. However, if you are driving
on a straight road, and you notice the dots
constantly dropping down or heading up as you
drive, the navigation unit’s yaw sensor is defective.
You can touch Reset to clear ANG-Disp, and dotted
lines.
If either test above fails, please enter Yaw rate
sensor defective for the problem description, on
the Navigation core return form.
NOTE: The CCW, CW and Set buttons are disabled,
and cannot be activated. Use this screen to confirm that the navigation unit is
properly receiving input signals. Signals equal to (0) are
OFF, and signals equal to (1) are ON. If the value on the
display does not match the actual vehicle status, then
check the wire carrying the signal.
 VSP-Vehicle Speed Pulse from ECM/PCM (Connector A (24P) terminal No. 15)
a) OFF (0) when vehicle is not moving
b) ON (1) when vehicle is moving
The VSP comes from the ECM/PCM as a dedicated
signal. Internally, the navigation unit compares the
actual VP on the map against street data to adjust the
pulse to speed scaling factor. As this scaling factor
becomes more accurate, the Level gradually increases
from 0 to 10 (see the Tire Calibrate diagnostic screen).  BACK-Reverse indication from taillight relay (Connector C (8P) terminal No. 7)
a) OFF (0) when the shift lever is in any position other
than reverse
b) ON (1) when the shift lever is in reverse
The Back signal is used by the navigation unit to allow
the map screen to show the VP moving backwards
when in reverse. This signal is needed because the
Speed Pulse has no direction indication.
