Agreed the NAV-TV is very good but they are taking too much $$$. If you figure a GB i'm in. Interesting to see if the 2016 will have it or will Ford wait for 2017 to introduce to all trim levels. Seeing its on the Titanium it would be an easy "new" 2016 feature.
The Focus guys gave up on this for the same reasons
In addition ford will only program to "AS BUILT by VIN" so you still will not get it to work except by using the aftermarket.
