I pushed something on my radio and now I can't get it back to where it was. Satellite working fine, in FM mode there is a blue x in the preset display. Now when I push up/down it goes frequency up/down instead of channel up/down. I read the manual twice and can't figure out what I have done. Also, when you touch the channel on the display it would show artist push again, song title that is not working either. Interesting some photos in the manual show the x but don't expailn it. Thanks in advance.
