that part number isn't really coming up with many results...

you can get the current part number by going to http://gmnavdisc.com and looking it up for your car
(it will cost $200 there but you'll have the newest one direct from the only legit source of new map discs)

or you can try ebay (http://shop.ebay.com/i.html?_trkparms=65%253A12%257C66%253A2%257C39%253 A1%257C72%253A4726&rt=nc&_nkw=escalade+nav+map&_dmpt=Car_Audio_Video&_sticky=1&_trksid=p3286.c0.m14&_sop=1&_sc=1) for used map discs on the cheap and new discs of questionable source

ashkanani,

I did not pull up that part number from the Nav Disc website. I did do a search for your vehicle and I found one disc available. Here is the link: http://www.gmnavdisc.com/disc-search.asp?lang=en&make=CAD&model=ESCA&year=2007

Did your local dealership tell you that part #20774148 was the one you needed?

Thank you!

Interesting, does not sound like issue with the disk, but the nav unit itself.

Why doesn't the dealership just take care of this for you? I don't think it's something that you can do on your own...

although you can order that disc (apparently free of cost) from the nav disc center

you will have to order one from the nav disc center
digital copies of these discs are 'technically' illegal

https://www.gmnavdisc.com/disc-search.asp?lang=en&make=CAD&model=ESCA&year=2007

try that link... it should look like the picture I posted earlier... that disc you want is listed and costs $0.00 !!

you can order directly from that website, or you can call them and order via the phone

http://img37.imageshack.us/img37/9821/gmnavdisc.jpg


I have run into the same problem with my navigation system in my 07 Lucerne CXS. After doing the research I have found that my firmware version currently in the radio is a "100E", this disc in question (p/n 20774148) updates the radio to version 100F or greater and allegedly remedies the problems I am having. My immediate problem is since I am not a dealership, that disc is not available to me on the gmnavdisc website. Also, after inquiring with local Buick/Caddy dealerships they want to charge me $125.00 just to diagnose the problem...This I find ridiculous since I already gave them the solution...a FREE disc. Is there any other way I can get a hold of a copy of this disc without being a dealership. I even went as far as to call the navdisc number and they basically told me they can only send it to a dealership. If anyone could offer ANY help, I would GREATLY appreciate it. Thanks in advance.

Just to be clear, my problems and the fix were documented in GM Technical Service Bulletin 08-08-44-013C as seen below:

Subject: Navigation Radio Intermittent Blank/Black Screen, Map Disc Read Errors, Features Not Accessible While Driving, Navigation Radio Resets Upon Startup (Update Navigation Radio Software)
Models: 2006-2008 Buick Lucerne
2008 Buick Enclave
2007-2008 Cadillac Escalade Models
2007-2008 Chevrolet Equinox
2008 GMC Acadia
2007-2008 Pontiac Torrent
2008 Saturn OUTLOOK, VUE
All Equipped with Navigation Radio (RPOs U3R, UZR, U3U, UVB)

Attention: This bulletin applies to vehicles sold in the U.S. and Canada only.
This bulletin is being revised to update models, model years and software calibration information. Please discard Corporate Bulletin Number 08-08-44-013B (Section 08 -- Body and Accessories).

Note: The software contained on this Service Update Disc (P/N 20774148) for 2009 MY has been revised. If the vehicle is a 2009 Model Year, refer to Service Bulletin #09-08-44-002.
Note: If the vehicle has a 2008 MY radio and the software version is 100M or higher (e.g. 100N) for the SuperNav navigation system (Escalades) or 100F or higher (e.g. 100G) for the BlackTie navigation systems (Lucerne, Enclave, Equinox, Acadia, Torrent, Outlook, and VUE), the improvements/corrections offered via update disc 20774148 are already installed and this update is not required. The screen will display the following message "The disc installed is not a MAP DVD" THIS IS NOT AN ERROR MESSAGE.
Condition

Customers may comment on any of the following conditions:
The Navigation Radio display intermittently goes blank or turns black/off after switching video sources. This most commonly occurs when the shift lever is transitioned from PARK to REVERSE to DRIVE (or vice versa). Other possibilities include switching to DVD movie or Rear AUX (if equipped).
The Navigation Radio screen may intermittently freeze, lock up or display "MAP DVD Read Error" messages.
Some features may not be accessible while driving. This includes scrolling lists, address book and navigation related entries (i.e. entering a destination).
The Navigation Radio, upon startup, will continue to display the vehicle logo repeatedly. This condition occurs when the vehicle language has been changed, using the Driver Information Center (DIC), in the previous ignition cycle.
Cause

These conditions may be caused by software anomalies.
Correction


Update the Navigation Radio software.
Do not replace the Navigation Radio.
Technicians are to update the Navigation Radio software using a software update disc, P/N 20774148. The software update disc is to be obtained from the GM Navigation Disc Center, using the contact information below. Follow one of the two procedures below as appropriate for the vehicle you are working on.
Navigation Radio Software Update For Cadillac Escalade Models 2007-2008
Note: If the radio has software calibration 100M (2008 MY radios or earlier) or higher (e.g. 100N, etc.), the software corrections contained on the update disc 20774148 are already installed and this update is not required. The screen will display the following message "The disc installed is not a MAP DVD" THIS IS NOT AN ERROR MESSAGE. To check the software version follow steps 1 and 2 below.
Important: For the condition regarding features not accessible while driving, this will only be addressed in 2007 and 2008 model year Cadillac Escalade vehicles.
Start the engine, with the gear shift in PARK, wait until the audio or navigation screen is displayed after the opening screen (you may have to press the OK button on the Caution screen).



Proceed to the FM audio screen and confirm the current navigation software version by pressing the CONFIG and SEEK UP buttons (1) simultaneously. 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. Refer to the illustration above which shows the two buttons that need to be pressed. The navigation software version is the first four characters, reading from the left, located in the middle of the screen.
If the navigation software version is 100M (2008 MY or earlier) or higher, the radio has the latest navigation software available and no update is necessary. However, if the string of letters across the screen are NON-ASCII letters, this indicates an internal communication problem with the RADIO. Refer to the Diagnostic Starting Point-Cellular, Entertainment, and Navigation procedure to begin the diagnosis of the customer concern. For all other navigation software versions proceed to step four to continue the software update.
Important: Do not turn off the power or remove the update disc while the software update is in progress.
Important: This software update procedure will erase the customer's Address and Destination entries from memory.
Eject the map disc from the top map DVD slot, callout (2) in the illustration above, if present. Load the software update disc, P/N 20774148, into the top map DVD slot.
The display will show "Update in Progress" and upon successful software upgrade, the screen will transition to a blue screen with "The disc installed is not a MAP DVD" displayed on the screen. It will take approximately five minutes to load the new software. Eject the software update disc from the top map DVD slot and retain at your dealership.
Confirm that the new navigation software version is 100M using the procedure in step two above.
Install the customer's original map disc, if it was present. If the customer concern was related to limitations while driving, confirm that the "Limit Features While Driving" feature is turned off by pressing the CONFIG button followed by the Radio tab and "Limit Features While Driving" tab. "Limit Features While Driving" should be unselected to match the customer's preference.
Verify proper operation of the Navigation Radio.

Open the front display by pressing and holding the EJECT (1) button for approximately 15 seconds. Eject the map disc from the revealed map DVD slot by pressing the EJECT (2) button located beneath the revealed map DVD slot. Load the software update disc, P/N 20774148, in map drive (3).

let's make sure i understand what you're saying...

you went to your dealer and said: 'here's this bulletin that i found that describes my exact situation'
they then said that they would still want to charge you a diagnostic fee?

if that's the case, call another dealer... eventually you will get one that says - 'ok we'll perform the bulletin and it will cost you $xxx'

LucerneCXS
09-17-11, 03:30 PM
Yes, that is what happened. I told them about the bulletin and about the problems I was having and the guy said...and I'll quote to the best of my memory: "Whoa whoa, let's not jump to conclusions about the bulletin. We'll have to do a diagnostic and maybe even have to hook it up to a laptop and download something from GM, and then maybe it will be the disc. If it is the disc we won't charge you for that just the diagnostic." And then I asked what the diagnostic would cost me and he replied with "$125.00". I just said thanks and hung up. I couldn't believe it. I gave them the solution and it will still be a diagnostic, awesome. it is a 5 minute install process and no technical skills are even required...put the disc in...wait...take the disc out. Oh well.

RippyPartsDept
09-17-11, 03:33 PM
i can see that they don't want to just jump into a situation based on a customer's own diagnosis and that's their right as a business to stick to their own policies for diagnostics

see if you can find another dealer who's willing to work with you - or maybe send an email to their service manager
