Navigation System Malfunction (and SD Card Errors): Notes

WARNING: This page is about a different car, the 2018 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

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 (IO6 with CW1) Auxiliary Audio Input Malfunction (IO6 without CW1) Auxiliary Audio Input Malfunction (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 reference table)
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.
