update worked flawlessly on my 2010 m3 which had 2009 maps. Even though i didnt' have the check box it worked via USB. Connected my car to a battery charger as it did take a while.
I didn't have a USB thumbdrive so i just used a 32gb CF card reader. For anyone w/out a 32gb you can also flash with 8gb memory cards / usb drive as it only needs 8gb @ a time although may take longer.
my 2011 x5m also went from 2010 maps to 2014-2 on problem.
Didn't notice any new features or 3d building but updated roads.
