The PO installed an aftermarket radio/tape deck in my car. As you probably know, the rear glass contains an array of three antennas which are normally selected by the car (any one or a combination there of). With an aftermarket radio, as i understand, the car defaults to one of the three antennas. It is for this reason i believe that the radio gets terrible reception as it is now, or it is not plugged in to the antenna at all, i dont know much about radios. My brothers acura, however, does not have an antenna. It was "shaved" after the power up/down stopped working. When i was playing with his radio last night i noticed that it still got perfect reception although antennaless. Upon this discovery, i came to the conclusion that the radio must not be plugged into the antenna at all or it is a really crummy radio. What i really need is a diagram (preferably a picture with labels) to ascertain as to whether or not the antenna is plugged in to the radio at all.
