I live in Los Angeles and just purchased a 2005 S80 (only 10K miles for a great price of $25,900). Well, the AM Radio reception was awful. So when I got it home, I called two of the nearest dealer service centers. They both said the fix is easy: they install a small metal plate/strip in the pillar by the rear window. Well, now my AM Radio is working like a champ! Here's the info on it: I beleive that it was a secret recall item a couple of years back. There is a service bulletin (tech note 39-35) out for this problem. Dealer fix was free and simple. Reception improved 1000%. repair order said "99042-2 antenna amplifier 1 side modifying according to TJ" the part was 30657370. evidently this is a known issue by Volvo and they have this "fix" for it.
