Hey guys,

When I bought my 07 sts4 it didn't have navigation installed. GM doesn't sell the discs anymore. I bought one off of ebay. I loaded it into the DVD rom and it takes it and closes with a lock but nothing happens. I put it in the cd/DVD just to see and it said "disk copy protection error". I flipped over the DVD and it looks like it could have been burnt. My car or the DVD?

If I remember correctly, 07 and earlier STS with the nav had to have a system update to be able to use the later nav update disks. Never had to do it myself because I have 08s. There are 2 disks and dealer or someone with a TechII had to do it. Many dealers have lost these disks and do not remember. Good luck in finding a dealer who has the disks and remembers what to do. Some members of this forum have the disks and have done the update themselves. Good Luck.

Pretty sure the GPS firmware update would include this (which he could do himself). However, I am not sure it has been verified to work on 07s.

OP, do you have mag ride? If so are the controls on the main Config screen or buried?

Thanks! I thought so and I had called the dealer before I even tried to install it. When I called the guy at the dealer he acted like I was an idiot and said it should just install when you put in the disc.

I do, it's on the main config screen. How would I go about updating the firmware myself?

If you have the controls on the main screen then I think you have the dual layer firmware update. Not sure what to do next except try a different disc.

Ah, so no point in getting to calling a dealer to see if they could update then if it's already updated? Is there a screen somewhere that says the firmware version to confirm it's got the update?
