I am looking at doing this. I found where I can order the parts for $355 through Levittown Ford Parts and according to them, you don't need a dealer visit to do this. I called Both my Ford dealers in town and I got the run around and told $799 installed. I mentioned that from what I have read it is a simple install, maybe 20 minutes and he stated they had to "program" it. I'm just making sure if I order this, I won't need to have the dealer do anything. Its unfortunate these Ford dealerships don't care if they screw you over or not.
