Recently i added the Downhill Descent control (switch and Forscan programming); works like a charm. While I was in forscan I also changed to allow Nav address entry while the vehicle is in motion. Once this was done my Travel link disappeared. I changed back to allow the Travel link to reappear and now Im unable to enter the address at all; I get a message indicating the address cant be entered while the vehicle is in motion. Only problem is the vehicle is sitting in park. If I go back to change again; Travel link again disappears but the Nav address while in motion and while sitting still are now functional. Mine is a 2015 F150 with Sync2.
