Sirius Radio Presets

Picked up new 2013 750 Li x and set up Sirius radio while driving home. Set up presets along with some AM & FM channels. When I started the car the next day, all of the presets were gone and the radio defaulted to 184 (preview channel). After 8 days at the dealer, it was returned to me with the statement "that's the new design" and all 7 series will have this issue. I drove the car home and called Sirius. They sent another signal and then said it is a problem that BMW is having and they cannot help. BMW from what I was told is not addressing this problem as they do not see it as a problem. Now the worst, every time I start my car the radio goes to 184 and no ability to save Sirius radio channels in the car. Anybody else have this issue?
