I have just replaced the battery in my x reg 1.8 ford mondeo duratec, once reconnected the radio wanted the radio code which i found on a sticker in the book along with the radio code etc, when entered it is not accepting the code, I cannot get the unit out either to get the number from the side of it for dealer to do it! OK, there is something you can try if you have the radio code for the car. The display can sometimes be reset by disconnecting the battery for around five minutes and then reconnecting again. This allows the capacitive charge in the display to deplete and can sometimes get it working again. Hi all, My 2004 Mondeo has developed a strange problem. Tonight after work, it wouldn't start, and radio was working fine. The AA came out and said my battery had lost charged, so he recharged it a little and went on his way. Now the radio is switched on, but nothing out of the speaker. If you tu G8jY0.
