Does anyone know if the bracket for the dvd vibration tsb is installed in the 2005 armada's without the dvd? Hope that makes sense. I ask because I don't have the dvd installed on my 2004 but still have quite a bit of vibration over rough roads. Trying to get the dealership to bite the bullet and make it happen. They keep tightening thigs up which helps some, but eventually loosens up again. Thanks.
