: Sluggish Audio interface STS-V

It takes like 5 seconds each to change CD tracks on my STS-V also sometimes there is a 5 second delay before the volume reacts to inputs? Is there a flash update that corrects this?

There is a TSB; I don't have it handy at the moment; but if someone can't bring it up and paste it I will track it down for you tomorrow; It corrects several other issues as well.

Voice Recognition System Performs Poorly, Memory Seat Function Operation Complicated, Navigation Radio Screen Locks Up, Map DVD Message Displayed, Telephone Number Not Dialed via Bluetooth #05-08-126-001A - (01/18/2007)
Models: 2005-2007 Cadillac STS
Built Prior to December, 2006
with Navigation Radio (RPO YQ4)

This bulletin is being revised to add additional conditions, update the service procedure and revise the part ordering information. Please discard Corporate Bulletin Number 05-08-126-001 (Section 08 -- Body & Accessories).


Some customers may comment of any or all of the following conditions:
Poor performance of the voice recognition system.
The memory seat function operation is too complicated to set.
The navigation radio touch screen locks up.
The navigation radio displays "Disc Inserted is Not a Map DVD" even though a map DVD is installed.
A telephone number cannot be dialed via "Bluetooth". This occurs after the customer has added and/or deleted more than 50 inputs.
When using "Bluetooth", the outbound caller is very faint and cannot be heard well.


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.
3. Wait until the audio or map screen is displayed after the Cadillac logo screen.
Important: If the navigation system software is the same or higher than version 0FC, the software update will not start and the navigation software update is not necessary. 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.
10. Use the Tech 2 to complete the following steps to initialize the audio and navigation software:
10.1. Select: Diagnostics
10.2. Select: Model year
10.3. Select: Vehicle type
10.4. Select: Product make
10.5. Select: Product line
10.6. Select: Product series
10.7. Select: F7 Body & Accessory
10.8. Select: Entertainment
10.9. Select: F5 Module Set-up
10.10. Select: F2 Navigation Radio
10.11. Select: F0 Audio Update Initialize (takes approximately 30 seconds)
10.12. Select: "Next". Note: A loss of communication will be experienced, power the Tech 2 off and then back on and follow steps 10.1 through 10.9, then proceed to step 10.13 to continue initializing the Navigation system.
10.13. Select: F1 Navigation Update Initialize (takes approximately 30 seconds)
10.14. Select: "On". The "Commanded State" will switch from "none" to "on" and the screen will flash and come up to the radio display.
10.15. Exit back to the "Body/Accessory" screen then select F7: Body/Accessory
10.16. Select: Entertainment
10.17. Select: F4 Module information
10.18. Select: F1 Navigation radio. Verify that the software versions are:
- Navigation system software version = 0FC1
- Audio system software version = 010C
30. Cycle the ignition to OFF.
31. Open and close the driver's door and wait for 60 seconds.
32. Cycle the ignition to ON.
33. Load the customer's map DVD into the lower slot located below the navigation system screen.
34. After inserting the map DVD, touch the "I agree" screen button. If the "I agree" screen does not come up, select the "globe"/map key to access the navigation screen.
35. Reset the radio presets to the customer's preferences.
36. Verify that the navigation system reflects the correct location of the vehicle. If necessary, recalibrate the navigation system. Refer to the STS Owner Navigation Manual supplement (pages 2-59 and 2-60) for more information.
37. Cycle the ignition to OFF. The software update is now complete.
