i recently bought a factory navigation system on ebay it was removed from a 04 seville. The unit pluged in to my factory harness with no problem and when i drive the map shows my correct position but the arrow stays in one direction no matter whether i am driving north , south,east or west and when i enter a destination if highlites the way to go but the guidence doesn't start so when it is time to turn i wont inform me to turn or anything i think i might need a peed sensor wire but i am not sure. The other problem i have is it seems like as soon as i hooked up the navigation my dimmer fuse blew i am not sure if the radio has anything to do with the fuse blowing but as soon as i replace it it blows again when i turn the lights on any imformation will help
Thanks in advance for any advice.

The 2001 Cad used On-Board Navigation System (RPO UY4). The 2002 and up used Advance Navigation System (RPO U3R). There may be significant differences in the interface. So the way it communicates with the vehicle for dead reckoning (vehicle speed and direction) may be different. This is a unit self test for the 2001 unit (Minus illustrations). You might want to get a factory manual via DVD (there's were some priced very reasonable on eBay) and spend some time comparing circuitry.

Navigation Diagnostic Self-Test Features
Accessing the Diagnosis Menu Screen
To enter the navigation self-diagnostic mode, perform the following procedure:

Turn ON the ignition, with the engine off.
Disable the clock button on the navigation display head (NDH), as follows:
Press the audio ADJUST button on the NDH. The audio adjust screen appears.
Use the CLOCK ON/OFF soft key to disable the clock button.
Test the clock button to make sure it is disabled. The clock button, when enabled, appears in the upper left corner of every screen. The button toggles the clock display on and off.
Press the audio MENU button on the navigation display head (NDH). The audio main menu screen appears.
Quickly repeat the following sequence three times:
Touch the left upper corner of the screen of the navigation display head (NDH).
Touch the right upper corner of the screen of the NDH.
The navigation display head (NDH) beeps once and the navigation self-diagnostic main menu, titled DIAGNOSIS MENU, appears.




(1) Left Upper Corner of Screen - Touch Sensitive Area
(2) Right Upper Corner of Screen - Touch Sensitive Area

Diagnosis Menu
The Diagnosis Menu screen has seven buttons. The top two buttons, LINE/DEALER and INSPECTION, have no function; they serve as functional titles for the buttons below them.

The buttons below LINE/DEALER are:

SYSTEM
DIAG MEMO
VEHICLE SIG
The buttons below INSPECTION are:

DISPLAY
NAVI
Each of the five buttons, when pressed, leads to a menu or set of submenus which may be used to perform various navigation self-test procedures.





System Check
Pressing the SYSTEM button on the Diagnosis Menu screen initiates a self-diagnostic test of the navigation system. Once this self-running test is complete, the SYSTEM CHECK screen appears. If everything is normal, this screen displays:

NAVI OK
CDROM OK
GPS OK
DISPLAY OK
Press the DIAG MENU button on this screen to return to the Diagnosis Menu screen.





Diagnostic Memory Display Menu
Pressing the DIAG MEMO button on the Diagnosis Menu screen leads to a screen titled DIAG MEMORY DISP. This screen has four buttons, and each button, when pressed, leads to a submenu. The four buttons are:

NAVI
CD-ROM
GPS
DISPLAY
These four menus are used to display system internal diagnostic codes. Each internal code that may be displayed on one of these submenus has an equivalent scan tool diagnostic trouble code (DTC). For that reason, the specific internal diagnostic codes, as read through the Diag Memory Display screen, will not be listed in this section.

Press the DIAG MENU button on this screen to return to the Diagnosis Menu screen.





Vehicle Signal Menu
Pressing the VEHICLE SIG button on the Diagnosis Menu screen leads to a screen titled VEHICLE SIG. This screen displays several system parameters, as follows:

Gyro voltage (GYRO VLT)
Offset (OFFSET). Displays the center voltage when the gyro stops.
Speed signal (SPEED), displayed in km/h.
Reverse signal (REVERSE). A zero (0) in this field means no reverse signal is present. A one (1) in this field means that the reverse signal is present.
Gyro (GYRO). Displays the relative bearing. This value changes when the vehicle turns.
Distance (DISTANCE). Displays the tire coefficient that is used during distance correction.
Press the DIAG MENU button on this screen to return to the Diagnosis Menu screen.





Display Inspection Menu
Pressing the DISPLAY button on the Diagnosis Menu screen leads to a screen titled DISP INSP MENU. This screen has five buttons, and each button, when pressed, leads to a submenu. The five buttons are:

HARD SW
TOUCH SW
PRG VER
BRIGHT
COLOR BAR
These five submenus may be used to test the navigation display head (NDH) hard keys (on each side of the screen), the complete touch screen, and the screen colors, brightness and contrast. The submenus are described below.





For export vehicles with television (UE7), the DISP INSP MENU screen has six buttons. The sixth button is TV. Pressing the TV button leads to a submenu, described below.




HARD SW
Pressing the HARD SW button on the Display Inspection Menu screen leads to a screen titled HARD SWITCH. This screen shows the name of each hard key on the navigation display head (NDH). When the pressing of the hard key is recognized, the color of the switch on the screen changes to yellow-green.




TOUCH SW
Pressing the TOUCH SW button on the Display Inspection Menu screen leads to a screen titled TOUCH SWITCH (V). This screen has a grid of numbered vertical lines. When the touching of the line on the screen is recognized, the line disappears. Pressing the NEXT button on this screen leads to a screen titled TOUCH SWITCH (H). This screen has a grid of numbered horizontal lines. When the touching of the line on the screen is recognized, the line disappears.







PRG VER
Provides the navigation display head (NDH) software version.




BRIGHT
Pressing the BRIGHT button on the Display Inspection Menu screen leads to a screen titled BRI/CON. This screen is used to test the screen brightness and contrast. Brightness and contrast, if changed with this screen, revert back to their original settings upon exiting the diagnostic self-test.




COLOR BAR
Pressing the COLOR BAR button on the Display Inspection Menu screen leads to a screen titled DISP COLOR BAR. This screen may be used to test the display color to make sure that the color band and the color name above the band match.




TV (UE7 Only)
Pressing the TV button on the Display Inspection Menu screen leads to the TV Adjust screen. This screen may be used to test the television tuner functions, the television antennas and the television screen adjustments (color, tint, contrast and brightness).





Pressing the ANT button tests all of the television antennas, one at a time, in sequence. As each antenna test proceeds, the name of the antenna under test appears on the screen in the square field next to the ANT button. The antennas are ANT1, ANT2, ANT3, ANT4 and DIV. The quality of the television picture on the display indicates correct antenna function.
Pressing the TUNE + or TUNE -- button changes the television channel up or down. The current channel number appears on the screen in the TUNE button.
Pressing the ADJUST button leads to a screen which may be used to test the television screen brightness, contrast, color and tint. These settings, if changed with this screen, revert back to their original settings upon exiting the diagnostic self-test. Pressing the RET button returns to the TV Adjust screen.



Return to Display Inspection Menu
For each of the inspection submenu screens described above, press the DISP MENU button to return to the Display Inspection Menu screen.

Navigation Module Diagnostic Menu
Pressing the NAVI button on the Diagnosis Menu screen leads to a screen titled NAVI DIAG MENU. This screen has three buttons and each button, when pressed, leads to a submenu. The three buttons are:

PROGRAM
RGB INFO
GPS INFO
These three submenus may be used to test the navigation module (NAV) color signals and GPS information. These submenus are described below.




PROGRAM
Pressing the PROGRAM button on the NAVI DIAG MENU screen leads to a screen titled PROGRAM VER. This screen displays software version information and the hardware part number for the navigation module (NAV). Included on this screen is a VERS UP button. This button may be used to update the navigation module software. Do not proceed to the PROG VERS UP screen unless you have the program disk available and the necessary instructions to perform this update.




RGB INFO
Pressing the RGB INFO button on the NAVI DIAG MENU screen leads to a screen titled RGB CHECK. This screen may be used to test the color signals sent from the navigation module (NAV) to the navigation display head (NDH). Five color bars are shown. They are black (BK), red (R), green (G), blue (B) and white (W).




GPS INFO
Pressing the GPS INFO button on the NAVI DIAG MENU screen leads to a screen titled GPS INFO. This screen displays the status of the navigation GPS system. This screen provides the following information:

SATELLITE. Shows the number of satellites received. Normal system operation has three or more satellites being received.
ANTENNA. With normal operation, this field displays OK. If the GPS antenna is open, this field displays NG.




Included on the GPS INFO screen is the SAT button. Pressing this button leads to the SATELLITE INFO screen. This screen provides specific parameters (latitude, longitude and condition) for each satellite received. If the condition (CND) field is blank for a particular satellite, the satellite is not being received.

Note than when checking satellite information, the vehicle must be outside in an open area. You can not check GPS information inside a building; the navigation system does not receive GPS information inside a building.




Return to Navigation Module Diagnostic Menu
For each of the submenu screens described above, press the NAVI MENU button to return to the NAVI DIAG MENU screen.

Exiting the Diagnosis Menu Screen
To exit the navigation self-diagnostic mode, perform the following procedure:

Turn OFF the ignition.
Open and close a door.

This is the exact same issue I'm currently having (now that I have an antenna long enough)

beemc, if you're still around, what did you do to fix it? I just purchased the unit from e-bay as well. (Schramm Auto)
Wondering if it's the unit, or a wiring problem in the car.... Though probably the unit for the gyro.... I would think, anyway.....
