Has anyone successfully copied a GM Navigation Disc that actually will work in the Unit? I have made about 6 coasters so far, I have used Alcohol 120%, and DVD Decrypter to create and burn an ISO image, but the unit reads the DVD as DVD, but then rejects it. Any help on how I might be able to make a working copy would be greatly appreciated.

Welcome ispperformance,

use the search function with the key word navigation as there are already some threads about navigation discs and read them maybe there's some more info.

GM uses safe Disc codes. You might try searching safe disc

Well I copied the disc successfully! The original disc was in bad shape, I even had Radio Shack shave the disc to remove some scratches and it still didn't work good. I did make myself 2 excellent working back-ups, one I use in the truck and the other in safe keeping. If anyone is interested let me know and I will share the info.

Sharing the info would be helpful for other users

Ok, after about $20 in DVD-DL Coasters I figured this out..... Software I used was DVD Decrypter to create the image, insert NAV disc, and then click decrypt. Keep in mind to keep the write speed as slow as possible 1x. I then used IMGBurn to burn my image, but first I used the verify feature to make sure the image and the disc were coherent. Know here is the part that makes it or breaks it. You have to have a DVD Burner that you can change the book type to DVD-ROM. I started using a Lite-On DVD Burner that I was able to change the book type in IMGBurn, but that didn't matter because the burner itself could not write DVD-ROM booktype. So I started researching my 3 DVD-Burners and Found that the Samsung in my work PC was the ticket. So when you burn the image using IMGBurn, make sure you have a dvd-burner that supports DVD-ROM booktype, and change the booktype to DVD-ROM in the IMGBurn Program. Next you want to burn the image as slow as possible 1x. This process worked for me, created create back-ups that I have tested on a few road trips. I hope this helps you guys, if you have any problems or questions let me know.

Could you give me the model # of the burner you are useing.
Thanks

I'm pretty sure it's a Samsung, I will check the exact model # when I am back in the office and re-post.

Thank you

GHUNTER, the DVD Drive is a TSSTcorp CD/DVDW SH-S162L (it's a Sumsung). If you have any other questions feel free to ask.

so i have read the previous replys and get up to the part where i am about to burn the image with IMGburn and then a NOTICE! pops up telling me the image file is too large to fit onto DVD+R disk and then asks me if i want to write image anyway. Am i using the wrong disk or should i just write anyway. Need some help. THX.

Welcome zacsterx,

you've to use a doubler layer disc.

Yes, you must use a DVDR-DL (Dual Layer) disc. I have heard of people compressing the data or just putting the areas they needed on a DVDR but I don't think it is an easy task. Better off spending the extra $$ to get Dual Layer discs and copy the whole thing.

For the GM Nav Disc, can anyone confirm whether or not the original is a +R or -R disc? I've tried both using the process above and both fail. I'm using a Plextor PX-760A; Reading the ISO with DVD Decrypter at 1x; Writing out at 1x using IMGBurn after flagging the Booktype to DVD-Rom. With the -R DL the navigation system flat spits it out with an error. Using the +R DL media, it takes it but then I get a Check Disc error on the display. Using Verbatim media for both the -R and +R's. My thought is that this must be a +R original because it takes longer to fail with the +R's than the -R's but maybe I'm wrong. Any other pointers would be appreciated as well.

Hi,

the original disc is neither +R nor -R. Such kind of media is only used with DVD writers. Commercially discs (DVD-ROM) are made in a totally different way.

So, should I be using +RDL or -RDL for my backup copy?

Hi all, new to this, I have made 3 working copies of the latest version of gm navdisc 15906573. I followed all the different ideas on here with not much luck. I finally decided to try this easy meathod.
Nero 7, copy dvd, set book type to dvd-rom, write speed as slow as possible. all settings at default except book type. The only issue i have has so far is it will not update radio. it starts but fails 1/2 thru. i used original disc to update nav unit, then removed original and inserted copy. has worked fine for a couple weeks now.

i use memorex dvd+r dl disc, sony dru-830a burner. use a sony 510a to read original. copy straight from disc.

thanks for the great info

Hi, chevytech01,
I would like to copy a 2008 Cadillac SRX navigation disc. Please send me an e-mail or PM with instructions as to what I should use. I have a DL burner and media.
thanks

I would prefer he does this in this thread if possible that's the purpose of the forum

I made a backup of the DVD in one try. Here is what I did. I read the navigation DVD with DVD decrypter 3.5.4.0. Go to MODE-->ISO-->READ. Select a destination file to save the image and click the DECRYPT button. Then I downloaded ImgBurn 2.3.2.0 and clicked on "Change book type." I have a Samsung DVD burner which is read as TSSTCorp CDDVDW SH-S203B. So I clicked on the Samsung tab and told it to change for DVD+R DL media. I changed it to DVD-ROM. Then I clicked OK. I selected the Navigation image for the source and set the write speed to 1x. I loaded a Verbatim DVD+R DL disc into my DVD burner. They were Verbatim (95310) 2.4X (Up to 6X) Double Layer DVD+R Branded in Cake Box Spindle 20 pack. I clicked the write button and had it verify. I put it into my 2005 Buick Rainier navigation system and it worked. The Buick Rainier has the same touch screen navigation as the Cadillac Escalade.

This forum helped me out. I hope this helps more people out.

Spread the knowledge.

Hey nellerig13, I am having the exact same problem. I thought it was working when I first put it in since it said it was automatically updating, however, after a few minutes, it said there was an error. I have enough coasters to last me until retirement and I wasted hella money on DL discs, but I am also too cheap to buy a nav disc from the store. PLEASE HELP!!!!! S.O.S.!!!!!!!! THANKS!

It will not work anyway.

Mr. Chef, sir, I have a 04 escalade and I went to www.gmnavdisc.com to find out which navi disc would be compatable with my car(2008 800 Trk/Mid-Utility/H3) , then I found it and just recently finished downloadeding this 7GB ISO file using a torrent program, I made a couple of copies using PowerISO, they didnt work. I was going to try using NERO 8 and change the recorder settings, burn speed, etc... but your saying that it doesnt work, well, I say if there's a will then theres a way.

I just want to know if I still needed a dvddecryptor or alcohol 120even though it's an ISO file extension. Also, I wanna know if anyone else obtained a NaviDvd the same method as I did, which is downloading it via .torrent, and was it sucessful? Any suggestions or ideas, please respond, thanks
