Re: Radio reception problem
I had this problem and like you thought it might be the radio. It turned out to the be the airel cable that runs from front to back. From the way that it runs though the car its quite easy for it to be broken and thus cause a bad reception. The previous garage had just shoved a bigger piece of wire though the outer cable in an attempt to pick up a signal.
You may want to check the grounding on the airel itself and that the connections are good. Also are you sure that they acutally replaced the lead?
