I'm not a car person, and I'm not a car stereo person, but I recently installed an auxiliary adapter in my car's stock radio, and it was surprisingly easy.  Once I figured out it was possible, I bought an adapter online and found a video that showed how to take apart my dashboard.  With a screwdriver, a socket wrench, a laptop, and about 10 minutes of free time, I modified my car stereo so it can easily interface with an iPod or any other portable music player.  I'm amazed at how awesome I am.  And at how awesome the internet is. #technology
