Thanks Gordon for your response, I have done a bit more research, and have been advised that if I diconnect the neg / terminal from the battery, I run the risk of having to recallibrate all the other features that my mondao has ie: cruise control, and etc .!! so I didnt go there.
This morning I took a trip to my local Ford dealer and asked them to remove the audio/cd player, thgen disconnect the power supply for a few mins. the reinstall enter the code (whic I had in the manual ta.)
and BOB'S YER UNCLE' pushed eject and they all came out. I was over the moon, for a couple of days earlier a Ford Dealer spokeman had said that I would have to get a reconditioned unit, cost plust fitting............£380.00!!!! So just for a nice 'drink' i was very pleased as you can imagin.
Cheers again for your kind offer of assistance. I need to get four of the exraction keys next so if it happens again I know what to do.
Regards
