What sort of issues? My only issue with the sat radio is it's not as clear as a cd, flash drive, or my iphone. Or the FM radio for that matter. It sounds kinda like a bad burnt cd from back in the day when you could first burn disks, after ripping music from napster.
Mine were all signal related, that now are fine with the MINI shorty. As far as sound quality it did get pretty crappy for a while, seems better...or maybe it is the shitty MINI stock sound system...
