All my previous cars and trucks with heated mirrors have the three wavy lines on the mirror or at least on the driver side mirror if it has heated mirrors.
My 24 badlands does not so not sure if the mirrors are heated.
My dealer wasn't as bad as yours, but when they installed my tow hitch they broke one clip and didn't replace it. Installed one of the tow hooks backwards and didn't hook the antenna back up for the proximity sensor.
For the price we paid for the LUX it should have a full digital dash, MyColor, Seat and side mirror memory, and a Bronco projection on the ground at night.
As far as complaints the ASS system sucks, it needs a V8!!, and adjustable head rest with the MGV seats. How cheep can Ford get. really.
