I also was going to say why dont you guys just get FM modulators. Their so easy to install and then you don't need to worry about reception. This is how they used to wire up CD changers to stock headunits.. of course now every new car has a CD player.. eventually I think every car will have something for Ipods and MP3s, but you can still use the trusty old FM modulator in the meantime.

An FM modulator is basically a device that attaches to your antenna wire and the music player (in this instance an IPOD). Then whenever you tune to a certain station, lets say its 90.5, it will be playing straight from the Ipod.
