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).
• Press the navigation BACK button on the steering
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 satellite
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.

By pressing and holding the MENU button for
2 seconds, a GPS Detail screen appears. This screen
displays real time incoming satellite positional data
when the vehicle is outside in the open. The
information shown on this screen is for factory use.
NOTE: The data shown in an example only.
• The box TS/AS and H Dop/V Dop is for factory use.
• The Speed and Direction information is updated in
real time when driving.
• The Date/Time Information is the same as in Setup
screen 2 Adjust Time Zone/Clock.
• If the 3D icon is shown above the yellow dots, this
implies that at least four satellites are available for
map positioning, and the GPS indicator on the map
screen will be green. See the Global Positioning
System detailed explanation in the System
Description.
• If the row of data in the table below begins with a
yellow dot, the AZI and EL fields can be used to locate
each satellite on the circular GPS diagram (see prior
screen).
NOTE: The table of values define the terms at the top of
the columns in the GPS Detail screen.

Tuning
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.

• Sensitivity study represents the status of the internal
tuning function. At initialization, this value starts at 6
and increases to 10 as the internal correction values
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.
