Satellite radio is not clear. It is at best slightly better than FM. This is because to save costs, XM/Sirius lowered the bit rate supplied to each individual customer in order to accommodate more users on the same equipment. I had XM years ago when it was fairly new and the quality was much better than it is now. It's so bad now that I decided not to renew my subscription after the 6 mo. trial that came with my car expired.
I have to disagree, I have had XM for 7 years, the sound is as clear as ever. Maybe you should take your car to dealer and check it out for problems. Also, your newer car may have a cheaper sound system than your other car years ago..Also, this is not internet streaming. Are you sure satelite has to share bandwidth like the internet does...I doubt it...It's "broadcasts" to all capable devices...Each device does not take up bandwidth...You are thinking of cell phone signal, or internet wi-fi signal...different technologies...where did you get your info? Satelite used digital signals that dont degrade with more devices..
