Honda radio code

either the radio code is wrong or you have locked the radio down you only have three attempts to enter the correct code if this is the case disconnect thenegative battery cable for 10 minutes then reconnect and try again. If the code is wrong the audio unit will have to be removed so you can get the serial number to give to the honda dealership so they can get the correct code

i purchased a bmw from a private owner need a code he lost the code

disconnect battery for about 10 to 15 minutes then connect again then turn radio on it will then ask for code and then hit power button
