i was just at my dealer yesterday trying to find out more about the 2014 I ordered. As of 3/6 they updated the tech package. Enhanced USB and bluetooth with smartphone integration was a separate $500 option, as of 3/6 it is now a part of the tech package and they increased the cost of the tech package from $3000 to $3150.
Besides the HUD and enhanced usb.. there is not any other differences I believe. When you select just the navigation system it adds all the other little things (i.e. bmw app, etc)
The top view camera is an additional option with the drivers assistance package. To get it you have to select the drivers assistance package for $950 then add the sub option top view camera for another $350.
