Hey Pennyfan
I also have the latest prof nav (HDD baseed) - I do get the 3D buildings though, but have only seen 'em once when I travelled into B'ham and it showed the Bullring etc in 3D (see post #17 above)
Mine also has 2008-2 maps on it - I was quite disappointed that the better spec nav came supplied with older maps loaded
I feel that the nav could be a LOT better and it cries out for 7 digit postcode search. Gets you almost there, but not quite
