<strong>Yahoo Message Number: 107335</strong>I just purchased a 2013 Ford Edge (3.5L). I am allowed to tow the Edge w/ 4 wheels down, ignition on and in natural. My question is; can I have installed a toggle switch the will disconnect the fuse to the navigation display in order to save battery power? According to the manual there is 1 fuse to the display. It's on as soon as you turn...
