WOW....I thought it was just me that was having this problem. Sometimes when going from CD to the radio I have to push the radio button several times to ge it to work. Also if I am close to a radio broadcast station the sound is great and if not the audio and music quality sucks. I know that I can get an external whip antenna, but that would mess up the looks of the car.
I e-mailed my dealer to see if this is a problem and they answered back that they have not heard of anything. Perhaps more of us need to voice this issue to our dealers.
