Mine is horrible as well. Ive had the truck about 10 miles from the broadcast tower and it still wasnt clear. When I'm about 25 miles away, its equally static-y. About 50 miles and over a mountain pass, its non existent where my multiple work use GMT900's and 2005 are crystal clear!
Its a night and day difference and totally ridiculous. I see the manual states something about FM reception is only good for 10-40 miles away and also states that Cell Phones can cause interference........HA
I Also hate the XM reception. Any light tree build up on the side of the roads and it cuts out. I'd rather listen to light constant static on the FM than a song cutting in and out on XM
