It's not a security update. This update is more like a complete rewrite and has very little to do with Microsoft. You see, for their first attempt Ford decided to outsource the project to a company called BSQUARE who put the UI together using
Adobe Flash Lite. For some reason, the results were
slightly less than stellar.
Anyway, the preliminary reviews of the new version sound promising so I am at least a little hopeful. I am still quite frustrated, however, that I've had to deal with such awful software for well over a year on a brand new vehicle that cost almost $40k.
