I have a 2008 Navigator L and just recently purchased a replacement remote fob. Every time I use the unlock button on the remote, the personal setting of the vehicle changes. The side mirrors readjust and the steering wheel adjusts as well. Now I can close the door and push one of the setting buttons on the side of the driver seat to go back to my original settings. But when I get out of the truck, lock, and the come back and unlock with the remote, the settings change again. Anyone out there can advise me on how to remedy this?
