Believe it or not, it has been my experience that if a stereo will not work until the antenna lead is plugged in, that it is due to the stereo not having a ground until that lead is plugged in. Anyone is welcome to correct me if I'm wrong (as I could very well be), but as Camel said, factory grounds are notorious for not working well/not working at all, and using the antenna for a ground is a half-a$$ed way of doing it (though it's still like that in my S13, heh). Your best bet would be to run a short wire to properly ground the head unit, as I will eventually do in my car someday. ;-)
