Well apparently it has!
I have just loaded this driver 'suite' onto my Mini 10v, (fitted with a 5530 card) which only had a basic Windows 7 installation, plus the recommended updates installed.
All the five or six drivers it contained were recognised and, as you say, even the GPS one appeared to install correctly, which it certainly didn't do before!
I am not quite sure how to find out if this feature will now work in the UK or not, but I do recall reading some posts on here from folks 'across the pond' who have had some success in this area... so a bit more 'searching' is still required.
What I am still not sure about though is whether there are actually two physically different cards, or that the 5530 is now capable of utilising the GPS capabilities here in the U.K, and if so what additional software would be required... Google Earth possibly?
I was almost starting to think that perhaps it was Dell who had made a 'typo', but now I am not so sure.... more 'investigation' is still needed I think!
