This bulletin is being revised to clarify which vehicles require the software updates by providing the software version information. Please discard Corporate Bulletin Number 05-08-126-001A (Section 08 -- Body & Accessories).

Some customers may comment of any or all of the following conditions:

These conditions may be caused by the navigation system software.

Important: After the software updates are complete, the customer may notice that some functions have been moved to different screen locations. Some voice recognition commands that were used infrequently have been deleted. If a voice command is not recognized, the navigation radio will now prompt the user to speak the command up to three times.

Technicians are to perform a software update on the audio and navigation systems using the following procedure:

1. Record the customer's radio station presets.
2. Connect a Tech 2® to the vehicle and cycle the ignition to ON with the engine off. This mode can be reached by depressing the lower part of the ignition switch for about 5 or 6 seconds. The upper button, with a circle on it, will illuminate. Determine the audio and navigation system software version numbers that are currently in the vehicle. If the vehicle has the software versions listed in the table above the software update is required. If the vehicle has any other software version the update is not required.
3. Wait until the audio or map screen is displayed after the Cadillac logo screen.

Important: If the navigation system software version is not listed in the table above, the software update will not start and the audio and navigation software update is not necessary. If the software update is not required DO NOT insert disc 2 into the radio.

4. Eject the map DVD, if loaded. Load the navigation system software update CD, disc 1, into the map DVD loading slot.
5. The statement "Preparing to load system software" will appear on the screen along with a progress bar. When the green progress bar reaches the end, the navigation software update using disc 1 is complete and the system will automatically restart.
6. Eject software update disc 1 from the map DVD slot.
7. Load the audio system software update, disc 2, into the map DVD slot.
8. A progress bar will be displayed on the lower left side of the screen. Japanese text will appear above the progress bar. When the yellow progress bar reaches the end, the audio system software update using disc 2 is complete and the system automatically restarts.
9. Eject the audio system update CD, disc 2, from the map DVD slot.
