Hyundai Repair: radio code, hyundai service, hyundai accent

Question
Good night, I took my car to a car wash and I had them clean the engine but for that they disconnected the battery and so the radio went off. When I started the car again it was requesting a code. I don't know which is it, can you help me please?
My car is a Hyundai Accent 1995. It's in kilometers so I guess it's Japanese but I'm not sure.

Thank you

Answer
The radio code should have been given to the original owner on a credit-card-sized card.  It's a four digit code that can be entered on the numerical radio buttons.

If you do not have this card, you should be able to obtain the code for the original radio by contacting your local Hyundai service center with the vehicle identification number.
