I have an 07 X5 with the original Nav DVD. I got a postcard in the mail from BMW offering me a 2011 DVD for $199. What advantage does the updated DVD have aside from new roads/cultural info? Is traffic ANY better? I live in LA and the traffic updates suck. Is the map format essentially the same? I don't like the way the roads are laid out and the colors are pretty boring to me. The picture on the postcard had a lovely Nav Screen shown with all these features mine doesn't have, but I'm sure it's the 2011 X5 version.
