I would love to hear Bubba back on Sirius. I'm not a fan of listening via cell phone while driving.
You need some inputs for your car stereo. I think I paid about 75$ to get a converter box to allow me to connect the headphone jack of my cellphone (or mp3 player etc.) to my stereo. I keep all the music/talk/audiobooks/radioio that I listen to daily on my cell phone so it was worth every penny.
