Year and a half on my 4.4, and the dealer just can't fix the AM radio. Reception is decent only in very strong signal areas. In moderate reception areas where my other car's AM works fine, and all my BMW loaners work just fine, the AM in my X5 is awful to entirely unusable: just lots of hash and "screeeeeeeeee." All of the availabe fixed were presumably tried. Anyone have such a problem actually solved? Or any creative thoughts?
