I have been researching this Ford kit problem for a while. I just got off the phone with the I datalink marketing guys. They are releasing a much better kit than the Advent or the Metra next month. its in production now. attached is a image of their kit!

In addition, they will be releasing a newer I datalink Sync controller, that should allow for enhanced Sync and vehicle controls, like doors, tires, ect.
