Buick Regal: Navigation System Malfunction (and SD Card Errors)
For issues with the Navigation system follow the steps below:
- Verify the radio has the latest software installed
- Verify the SD Card is fully installed and seated into the SD Card slot
- Verify the SD Card installed in the vehicle has the correct region and
part number
Check for DTC's, if any are present diagnose those first Diagnostic Trouble
Code (DTC) List -
Vehicle
- Test the X83 Auxiliary Audio Input, and if equipped the X92 USB
Receptacle with a compatible
USB device for audio playback.
If no audio is heard refer to Auxiliary Audio Input Malfunction (IO5/IO6),
Auxiliary Audio
Input Malfunction (IOB), or Auxiliary Audio Input Malfunction (IOR/IOS/IOT)
Ensure the SD Card is not removed with the ignition ON, this can corrupt the
SD Card and cause
navigation related errors.
- Ensure that SD Cards are not swapped from vehicle to vehicle, SD Cards
are VIN specific.
- If the read/write switch on the side of the SD card is in the incorrect
position any of the following
messages may appear on the display- "Once initialized, this SD card can only
be used for navigation in this vehicle" or "Navigation Service Expired" and
a loss of the current navigation
route may be experienced if the ignition is cycled. If the switch is in the
read-only (down) position
then this may be the reason for the messages. The switch needs to be placed
in the write position
(up towards the contacts). After placing the switch in the correct position,
re-insert the SD card
and verify the condition is no longer present. Be sure to emphasize to the
customer the SD card
should not be removed from the SD card slot.
In the event of an error code being displayed on the Radio Information
Display the information below
can assist in diagnosing the issue.
The following is an example of how to analyze the error code:
Example error code: 0x1.9845.9876.1123.9876
- 0x1 - Error code (see Navigation Error Codes)
- 9845 - Last 4 digits of originally paired VIN or "0x" if the value is
null
- 9876 - Last 4 digits of originally paired SD Card ID or "0x" if value is
null
- 1123 - Last 4 digits of currently obtained VIN or "0x" if the value is
null
- 9876 - Last 4 digits of currently obtained SD Card ID or "0x" if the
value is null
In this example the SD Card is paired to a vehicle with VIN ending in 9845
but it is installed in a vehicle
with VIN ending in 1123. Therefore, the SD Card is not valid and cannot be used
for the vehicle with
VIN ending with 1123.
The table below contains the error messages and error codes displayed on the
Radio Information Display
and the recommended action.

Circuit/System Description
The telematics communication interface control module is capable of
interpreting voice commands
received over the cellular microphone circuit. Speech recognition allows the
user to speak to one
computer in the vehicle, and one reached over the cellular communication
network. The module
attempts to understand the users command, and responds by speaking back, or by
taking the appropriate
action, e.g. dialing the phone.

NOTE:
- It is necessary to have the vehicle in an open outside area where
a
cellular call can be successfully placed and GPS data can be
received from satellites.
- The vehicle should be located in a quiet area.
1. Ignition ON/vehicle in Service Mode, press the blue OnStar Call button.
2. Verify that your voice is heard clearly by the OnStar Call center.
- If your voice can not be heard clearly
Refer to OnStar Microphone Malfunction (IO5/IO6/IOB) or OnStar Microphone
Malfunction (IOR/IOU/IOT/IOS)
- Go to next step: If your voice can be heard clearly
3. Verify that the system responds appropriately to all voice commands by
pressing the voice
command button and attempting to operate the system using multiple voice
commands.
- If the OnStar system does not respond to any voice commands
Replace the K73 Telematics Communication Interface Control Module
- If the OnStar system responds to some, but not all voice commands
For tips on proper pronunciation, refer to OnStar Description and
Operation (UE1 with IOB/IO6) , OnStar Description and Operation (UI3) , or
OnStar Description and Operation (UE1 without IOB/IO6).
- Go to next step: If the OnStar system responds to all voice comman
4. All OK.
