Not really. I am not sure as to where this originated - perhaps with Ford itself. However, you don't need a 32, a mere 8 will do (did for me). I suspect that there's something about unzippng the files that makes a difference, although I didn't bother playing with the different ways of doing it. If you use the built-in Windows unzipping utility - it SHOULD work. Having said this, I do have a NAV APIM, but I had no problems with installing either the 2.3 or the 3.0. I also disagree on the software update being 'out of warranty' - although this is a bit of a grey territory. Updates on the maps are not included, but - given that Ford does pimp out the new updates and has a web page dedicated to that, my view is that it is on them to ensure that those who are still within the factory warranty get the update, no stroking of the dealer required. Those mofos get all the stroke they deserve as it is.
