Cause



These conditions may be caused by a software anomaly.



Correction



Important



Before proceeding with the update, advise the customer that the Address Book, Previous Destination data, and Preset data may be removed during



the SW update. The user will have to input this data when the update is complete.



Important



- Do not eject the disc during the update.



- Do not turn the ignition off or remove power to the radio during the update.



- Do not leave the disc in the radio after the update.



- Do not give the disc to the customer.



- The software update disc may be used to update more than one vehicle.



Condition 1



For these conditions, follow this procedure:



Technicians are to update the navigation radio software using a software update disc, P/N 20884820. The software update disc is to be obtained from



the GM Navigation Disc Center, using the GM Navigation Disc Center Contact Information below.



Navigation Radio Software Update for Cadillac Escalade Models



1. Start the engine with the gear shift in PARK, and wait until the audio or navigation screen is displayed.



2. Proceed to the FM audio screen and confirm the current navigation software version by pressing the CONFIG and SEEK buttons (2)



simultaneously as indicated in the above illustration. If the screen switches, select FM to display the software version. Performing this



operation may take a couple of attempts for the radio to detect the simultaneous button press. The navigation software version will be the first



four characters (1), reading from the left of the display, that is located in the middle of the screen.



Record all information shown for later reference.



3. If the navigation software version is 101F or higher (e.g.101H), the radio has the latest navigation software available and no update is



necessary. However, if the string of letters across the screen is not alphanumeric, this indicates an internal communication problem with the



radio. For this condition, refer to SI. For all other navigation software versions proceed to step 4 to continue the software update.

4. Eject the map disc from the top map DVD slot (3) by pressing the EJECT button, if the disc is installed. Load the software update disc, P/N



20884820, into the top map DVD slot (3).



5. The display will show "Update in Progress" and upon a successful software update, the screen will transition to a blue screen with "The disc



installed is not a MAP DVD" message displayed on the screen. It will take approximately five minutes to load the new software.



6. When "The disc installed is not a MAP DVD" message is displayed on the screen, eject the software update disc from the top map DVD slot.



After this software update, the disc may be used again on another vehicle. Retain the disc at the dealership.



7. Confirm that the new navigation software version is 101F, using the procedure outlined in step 2 above.



8. Install the customer's original map disc if it was present.



9. Verify the proper operation of the Navigation Radio.



Conditions 1 and 2



For these conditions, follow both of the 2 procedures.



Navigation Radio Calibration and Software Update for All Other Models



1. Start the engine with the gear shift in PARK, and wait until the audio or navigation screen is displayed after the opening screen has appeared.



2. Proceed to the FM audio screen and confirm the current navigation software version by pressing the MENU and SEEK UP buttons (1)



simultaneously as indicated in the above illustration. If the screen switches, select FM to display the software version. Performing this



operation may take a couple of attempts for the radio to detect the simultaneous button press. The navigation software version will be the first



four characters (2), reading from the left of the display, that is located in the middle of the screen. The Radio Calibration will be the two



characters (3) as indicated in the above illustration.



Record all information shown for later reference.



3. If the navigation software version (2) is version 102C or higher (e.g.102D), and the radio calibration (3) is 40 or higher, the radio has the latest



navigation software and calibration available and no update is necessary. However, if the string of letters across the screen is not



alphanumeric, this indicates an internal communication problem with the radio. For this condition, refer to SI. For all other navigation



software and radio calibration versions proceed to step 4 to continue the software and calibration update.



4. A revised radio software calibration has been released to address these conditions. Reprogram the radio using the Service Programming



System (SPS) with the latest calibration available on TIS2WEB. Refer to the SPS procedures in SI.



5. During programming, the battery voltage must be maintained within the proper range of 12-15 Volts. Only use the approved Midtronics(R)



PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.

6. Open the front display by pressing and holding the EJECT button (1) for approximately 15 seconds. Eject the map disc from the revealed map



DVD slot by pressing the EJECT button (2) located beneath the revealed map DVD slot (3). Load the software update disc, P/N 20990141,



into the map DVD slot (3).



7. Do not push on the touch screen to close it.



Close the front display by using both hands at the four corners of the display until the display fits securely into the radio.



8. The display will show "Update in Progress" and upon a successful software update, the screen will transition to a blue screen with "The disc



installed is not a MAP DVD" message displayed on the screen. It will take approximately five minutes to load the new software.



9. When "The disc installed is not a MAP DVD" message is displayed on the screen, eject the software update disc from the map DVD slot (3).



After this software update, the disc may be used again on another vehicle. Retain the disc at the dealership.



10. Confirm that the new navigation software version is 102C, using the procedure outlined in Step 2.



11. Install the customer's original map disc if it was present.
