Jaydee, I'm not sure if this works or not. Probably not because nobody has reported back one way or the other. If you do try it I would be grateful if you could let me know if it has worked or not.
Before switching the radio on press button 6 and keep it pressed while you switch on.
Keep pressing button 1 until the first digit of the code is displayed,
then button 2 for the second digit,
then button 3 for the third digit,
then button 4 for the fourth digit,
then press button 5 and hold for a few seconds to enter and store the code.
Don't forget that if you get to "locked 13" it will then have to be recoded by a main dealer or a recoding service (cheaper option).
I hope this helps.
