Hi there, new to the forum, and just wanted to ask a couple of questions. I have just bought a 2nd hand 1.8 Zetec, and I think I have a radio problem. When it was purchased, the Ford dealer replaced the stereo with a newer 6000cd (silver central volume knob, and buttons), as the old one wasn't working properly. The problem is, that when you try to use the Balance /Fade button, I only get the option to 'Balance' and NOT 'Fade. Subsequently I can't get the rear speakers to work, the main front speakers and tweeters are the only ones working! I did manage to get the unit out, and all the plugs
