Yes, I know it's probably been done to death, but...
Changed the battery in the disco as it's for sale soon and I don't want the buyer to have any nasty 'extra' expenses. Natrually the radio needed the PIN sticking in afterwards. Charlotte tried this (accidentally hit the wrong number of the last digit). Long and short of it is, although she only did it the once, it's locked with the number she input displayed. How can I unlock the sodding thing?
