What does the nav update provide? Is it just a map database update or does it also improve the navigation?
My question comes from when I was using my nav, it recommended me do some stupid things. It did the short route and I suppose it was slightly shorter distance to get off on the off ramp and get back on to the interstate.
The map data seems to be fine for where I have been going?

Is the dvd in a 07 STS the latest out there?
