Duh....I had the wrong JCV file. I did 2 quick map upgrades to my 3760 - I must have missed the right JCV file when I did it the 2nd time for the 2014.10 maps. I seem to be messing up the simple things now, after getting through the 34xx upgrade relatively easy....

I really appreciate the help of this forum to do the upgrade. I don't miss having a 3597 at all now. And the interface between this and my wife's 2595 are now essentially the same...


One last thing.... I'm not sure whether I'm seeing the 3D topography with the upgrade. I have the 3D buildings showing fine. Is there a good route to check the 3D topography on?
