Hi.. I'm from Mexico and I have a 2008 Edge Limited with 6Cd radio player in the front and the family entertainment system in the roof for my kids... I want to change my 6cd radio player for the Nav System (in Mexico called "Ford Interactive System") Exist any posiblily to do this? What I need to do? I mean, without lose SYNC and the connectivity with the family entertainment system. Right now I can control the mayor of the family entertainment system functions with the 6cd radio player.
