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. 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.
