The Punto radio has 6 preset buttons to enter the code with.
Punto radio codes are between 1111 and 6666, so if the code you have has numbers above 6 then it is the wrong code.
The " WAIT " message means you have entered the wrong code too many times. You need to leave the radio and ignition switched on for up tp 2 hours until the display shows " CODE " then " - - - - " then enter the correct code.
