Re: New To This Forum And Fords........questions
Never used the aux or may never had it. Mine is a 2002. It had a 6cd changer located in the center console under the tray you remove.
Squeaking noise is a vibration you hear with the pads moving. There's spray for the backs that stops it. Could also just be contamination you can clean up by spraying brake clean on the pads as you rotate the wheels.
Hope this helps.
