The final nail in the coffin was Energy 92.7 announcing that they were going "all nineties". Energy 92.7 is the only radio station that I was likely to hear something I enjoyed on. Hell, it's the only radio station in the bay area with a greater than 1:1 music/commercial ratio, so you could say "hear music on" and be valid. But all nineties? Ugh. Time to give up on terrestrial radio.
So I got the Alpine 9857 head unit, the interface for my steering wheel controls, the Sirius satellite connector, and the I-Pod adapter installed by Bay Stereo in Mountain View.
Sweet. I hate paying for music, but at least I don't have to listen to DJs bitch and whine about the warts on their toes any more.
