I am very glad that somebody asked this question. I have had this problem since day one, and it only got worse when the top was down and it warmed up. My noise got so bad that I could barely satnd it--I even heard it over the
radio.
To my knowledge, Ford does not have an official fix for this problem. However, I am happy to report that at least in my car, I found the problem. The problem is not the
radio. In my car the problem was the
A/C vents above the
radio. I traced the noise myself and finally caught it mid-squeak one day when I pressed on the left lower corner of the vent piece---all this time I had been playing with the
radio. I had my dealer put a simple piece of felt around the vent--PROBLEM SOLVED.
Another problem I had was an obnoxious noise coming from the defroster vent---another plastic on plastic sound---but this one was worse than the
radio. The dealer solved this problem by ordering a new defroster vent and insulating that with the same felt. So far, so good.
Surely there must be others out there who have heard these noises. Am I in the major minority?
