In my 2013 Escape, with My Ford Touch, I use the iPhone 5s, and with the addresses added into the system, the format doesn't transfer over properly.  You can see the address but to implement it to the Navigation, I get errors, simply because the iPhone stores the country into its format, which seems not to work with the Sync/ My Ford Touch.

I have the iPhone 4s and also have a problem with about 1/2 the addresses not working with the MyFordTouch Navigation. In viewing the addresses I can't tell what is missing or wrong.
