Need up to date Navigation Disk for a 2003 STS

Recommended Posts

I need to find current navigation disk's for my 2003 STS with factory navigation. I have found no less than 10 versions available on E-bay. What is the current version and what is the cheapest place to buy them?

I recently purchased this car and the disk is out dated. I am in Kentucky which seems to be right on the border of the disk regions.

Additionally I am looking for a users manual for this year navigation unit. My car did not come with one and it isn't the easiest thing to figure out.

And while I am at it where can I find the cheat codes for this navigation to unlock features?

Any help is appreciated!
