I had the same issue. A few weeks ago when I logged into My Ford there was an option to update to v4.4 as I currently have 4.2.1. However when I went to do it last week it now says I am up to date. I called Ford and they said the v4.4 update was taken down as there is an even newer update available v4.5. This incorporates all the updates of 4.4 along with application updates as well. However, the Ford rep I was speaking with said this can only be installed at the Ford Dealer.
