ok i am new to the ford edge but here goes i bought mine used its a 2011 edge sel and i dont know if it came with navigation or not. i have the a5 card and i tried it but it says no device when i plug it into the sd card slot in the console is there another place for the nav sd card? how do i know if it came with nav originally? when i click on the compass it has the where am i button but it does nothing. also the 911 asist doesnt work???
