Absolutely no idea............
You might want to give us a clue....a little clue, like what car you are talking about would be a great start, then the model, maybe the year even?
What was the code for your radio? Maybe you can work it from there?
Did it equate to your VIN?
Have you used Google, I've heard it's quite useful to find answers to stuff........
The net says different things about this. All of them need the serial number from the top of the radio. One is to add 1212 to the last 4 digits of the serial (so like ...3456 would be 4668). Try that, some have had it work but there was a different formula for mine. I can't remember which one. If 1212 doesn't work for yours, take the radio out. Look at the top for the serial and call or go to a hyundai specialist. Usually that little help is free.
Getz 09. They have a Mp3 05 but the one we got from the wreckers is a mp3 03. Tryed google they say the 1212. 1111. 1222 and inputting the barcode itself but thay didn't work. Anyone have any other tricks to try
