Hi guys - just registered to pick your brains on this:

Got an old L-reg Mondeo Estate Ghia last weekend - top car for gigging!
The breakers I got it from managed to get the keycode for the radio but had no joy with the CD player. I was cleaning it out and subsequently found a card from a radio fitter with the codes written on it. Bonus.

BUT, I can only input the 1st and 4th numbers - I'm at a loss on how to input the 2nd and 3rd digits! I'm pretty sure all the buttons are working as I've tried holding other buttons down to see if it moved onto the next space whilst pressing the skip buttons but no joy as yet.

Any help will be greatly appreciated.

Cheers in advance
