Free Ford Radio Code Forum

Hi I need a code to get my radio working again. it is one of those 6000cd radio's. car battery died last night and replaced it today then this happens.. I scouted the internet earlier to try and get the serial number for the radio as its a 99 reg, I didn't get the car new and don't have the original documents for the radio.. I held buttons 6 and 1 and it gave me this code M6PDJ5, I'm not even sure if this is correct, If anyone can help me out here I'd really appreciate it. HAVE TO GET THE F'N THING WORKING!!!

Turn on the unit
Hold down buttons 6 and 1, and then release 6 (keep 1 pressed).
The unit will then cycle through a load of stuff. The first screen ends with the serial number of the device:
Mxxxxxx or to be removed
