Podłączenie zewnętrznego wyświetlacza LCD do radia samochodowego do wpisywania kodu

Hello everyone
I started repairing car radio for hobi 
the problem is:
the radio has a code but no display in radio (its have in car display)
and the risk is to blindly enter the code.
whether it is possible make some display to board only for typing code on which the radio will be able to connect .....
display from an old radio CD or DVD player....
Thanks....will be of great help to me

What radio? Brand name, model, somethinh?

philips CAR RADIO 22DC459/62F for Megane

Read memeory, upload file and we generate code.

My friend I have a code but my radio does not have a display, I fix the radio at home and I have to enter the code blindly,
my question is can some schema be found to connect any radio via data output to some display only for typing code
