I have a '94 940 sedan, 4 cyl. With 182,200 miles. I had a new radio put in for my daughter a while back. She hasn't used the radio, only the CD player. We went to use it, and the radio itself isn't working - the antenna doesn't go up. Fuse is fine, it worked before changing out the radio system. Suggestions on what might be going on? Did the guy (who's no longer around) forget to wire something when he installed the new system? Everything else works great.
