Register for the national Do Not Call registry. One more way the government knows about you.
Also, a few weeks ago a couple friends and I installed a 1/8″ jack into the center console of my Civic. The pictures are here. We drilled into one of the small punch-outs and installed a female-to-female adapter. On the other side of it is a cable that runs under the console, back through the molding on the front and into the stereo bay. You can see in the pictures the black cable that comes out into an RCA connector. All this is so I can hook up my iPod (or any other 1/8″ jacked device) into my car.
