Bad Fm Reception 2007 Yukon

[tommbo]

I have a 2007 Yukon Denali, poor fm reception. They changed the radio,antenna in the window,and module, checked all bulletins. Still no good. I would like to know if this is a popular problem with this new antenna. I am going to try to ask them to put a mast antenna in if they cant find the problem. also..when I open the rear door, the reception gets perfect, leading me to belive the window antenna is junk!!
