hmm this is possible because I had intended to hook up the tuner's antenna power to our power antenna line, (which I think I did) but I get horrible reception on AM (fm seems ok). Both of these problems don't concern me to much, cause I rarely listen to the radio, and the player doesn't seem to come on randomly, just stay on, so its not a big deal to pull out(usually do that anyway). In any case, it is really rare. Maybe if I had a better reason to take my dash apart...
