when I go to the website and configure exactly what you did, navigation is listed as 2150
I agree that the premium package 2 drops in price to 2100. This occurs when you have the Navi & Premium Package 2 selected. Likely since they share some features (such as enhanced BT & USB). If you deselect Navi, the premium package 2 price goes back up to 2650.
For the cold weather package being listed as 1000 instead of 1150, this occurs when you select the m-sport package. Not sure if there are any overlapping features at all, or if this is just a multi package discount scenario. If you select sport instead of m-sport, the cold weather package goes back up to 1150.
unfortunately navi never showed up as free on the site.
never read about the free nav for 5 series, but thats cool. seems like a pretty unlikely promotion to me, neat they did it once.
