I have a '08 M3 E92 with the option of Sirius satellite radio and frankly sound quality is fairly rubbish. When on MP3, CD or radio the sound is full and rich but switch over to satellite it sounds like a over compressed MP3. You know like there is someone playing tambourine in the background : ) I have only sat in one other BMW with satellite, an '07 335i owned by a friend of mine who says she never uses it as the quality is so poor. (sounds just like mine) Has anyone else been stupid enough to get this option and find the same thing? BMW of course say it sounds fineÃƒÆ’Ã†â€™Ãƒâ€šÃ‚Â¢ÃƒÆ’Ã‚Â¢ÃƒÂ¢Ã¢â€šÂ¬Ã…Â¡Ãƒâ€šÃ‚Â¬ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â¦ Thanks!
