How do you reset radio code for 2005 Mitsubishi Triton ute?

I'm assuming you have to code to begin with!

Turn on the radio so it displays "CODE"

Press and hold the "DISPLAY" button until it displays "0000"

Using the preset buttons 1 to 4, press the "1" button until it displays the first digit of your code. IE if you require the number 2, press it twice.

Press the "2" button until it displays the second digit of of the code, then press "3" button for the third digit of the code and "4" button for the fourth.

I can't remember whether I pressed the the display button or the power button or whether the radio just came on. I was just so excited and relieved I had music again...
