Right now I have Sirius radio. I got it almost 2 years ago. I bought a receiver for my sister for Christmas last year and she has not used it. I was going to take that one since it is a newer model, but then I have my old one. I didn't know if i could sell my old one to someone else. If I am not able to switch out the receivers, would i have to buy another one? Any suggestions? Also, I was also wanting to buy a house receiver kit to listen to at home? Any suggestions as to what kit and what website is best to buy that off of?
