I have a 1997 Saturn that I would like to put a CD player in. The dash stereo only has the AM/FM and Tape. How hard generally is it to install one with a CD option? My concern is the way the stereo is integrated into the dash... There is another version of my car that has a CD changer in the trunk. This car doesnt have the CD changer, but it does have an AUX on the radio, but does nothing. Is there a way to wire the AUX and place a CD changer in the trunk? Any help would be great! Thanks.
