I just purchases a sirius sportster and was wondering if there is a glass mount antenna available anywhere.  Also I saw that there is an interior windshield mount, much like a radar detector mount, that allows you to mount the regular roof top antenna.  How does that work? Do you get adequate reception?  Any thoughts or suggestions would be greatly appreciated.
