Hi I have just re installed my 600CD player and have tried to input the code. Buttons 1,3,4 let me input their number but No2 doesn't work. I have tried taking the removeable keypad apart and cleaning the board but it still doesn't work. Has anyone had this before, is it a component that can be replaced or is it a new one. The real pain is that its only to put the code in, after that I could live without preset 2, thats assuming it is the keypad. If anyone has experienced this please share the wealth of information. Many Thanks Danny
