I just found out I have a short in my tape/12disc combo. I need it replaced or repaired. I asked my service advisor to switch out the tape and put in a CD headunit which would control the 12 disc in the back. He informed me that you cannot use a CD headunit to control a 12 disc changer. I was wondering if anyone knew anyway to workaround this problem. I really want a cd up front (tapes are now useless), but do not want to get rid of my 12 disc completely.
