I'll second Oranoco on that.

A decent new CD player is next to nothing and the wiring adaptor will cost you about £10-12 and fascia about the same. The sound quality of the original Ford is really naff. You can also put 6x9 speakers in the doors that will improve it to no end, buit keep the old stuff and put it back in when you sell it

Oh and it cost me the price of a beer to get the coder for my last one from Fords, I think it usually costs about £10-15 if you dont know anyone that works there ...
