I suppose I could be nice and look it up for you. I'll need to know the serial number of the radio. You can remove it with a 2mm-ish allen, one screw on each side. It may be a special size, though. It depends.
If you have an "M" button between the + and - ( I think that's right....) then you can turn the key on, then press and hold that button for about 8 seconds. The serial number will display. If not the serial number, then scroll with either the plus or minus buttons, or the search buttons find the serial number.
Not all radios have this feature, yours probably doesn't. In any case, if you can get me the serial number, I can look it up.
Also, if you try to input a code 3 times and the code was wrong, it'll display "code wait". This means that you will need to keep the radio on for 1 hour so it can reset. Then put the right code in. Don't let the battery go dead. Use a charger if need be, and leave the key in the first position that the radio will power up in-accessory.
