please help me to give a  5 digit code.my original tape is kenwood,and it's serial number is: KE0778NO700379

Answer
Erdward,

  call kenwood .. since the unit is aftermarket they can help you get the code reset.. sorry i cant help you out anymore but i dont have the information to crack head units but kenwood can give you a generic code to reprogram it after you provide the proper serial numbers
thanks
