    This is my first post to the forum. I have a '06 Navigator with a dead THX head unit, and see the Lincoln LS units are available sometimes cheaper. I don't want to pop for a aftermarket unit at this time.

    If the top and bottom mounting tabs from a Navigator THX unit are installled on a comperable HU from a 'LS', can it be installed in the Navigator? The rear harness plug arrangement is the same, I don't know about the circuits. The only other difference I can see is that darker gray buttons on the LS unit.
