I took my van in to have the Nav / Satellite radio looked at. When I use Serius Radio or the built in navigation it keeps disconnecting and reconnecting. I haven't seen anyone post this problem but I found out from the dealer that this is a known problem and Fords solution to the problem is to wait for the engineers to come up with a solution. The Navigation still works even though it keeps disconnecting but you can't get through a song without it stopping the song once or twice when it loses signal. I have the 6'' screen with nav and Sync 3. So for now it kinda works as long as I don't use satellite radio. Just wondering how many others are having the same issue. Also wondering if Fords going to give me my six months of free satellite radio once this thing starts working properly.
