2012 NAV CIC update
My 2012 map update done by BMW does retain the 3D perspective feature. The version data shows 11211.2.18 Road Map North America Premium 2012.
I am not inpressed by the update of points of interest: Two restaurants I enjoy were not listed even though they were open about 2 years. One search yielded the prior name and the other had neither the old or current one at the address.
