Hyundai i20 - How to enter radio code

Recently I left my headlights on at night time by accident, so my car battery was completely drained. After the battery was recharged, of course the radio stopped working, and wants you to enter a radio code before it will work again. The funny thing is I have never had to enter the radio code, as the last time this happened, I drove to the Hyundai service centre to get a new battery and they fixed the radio for me when they gave me the car back. This time I did not go to Hyundai so I had to enter the radio code myself.

Unfortunately last time they did it, I did ask them what the radio code was, so the code is saved storely on my computer. So this time I just had to google how to enter radio code for Hyundai i20. Guess what - I cannot find it! It was not mentioned in the user manual either. I did find some general instructions for Hyundai cars for radio code, so I used that and it worked!

Here is the video with the correct title so it will help someone else do a lot less guessing/googling.
