I bought radio cassette ( KENWOOD ) for my car in year 2010 and when the car battery has been failed , the device has need operating code , and when I read the instruction manual , I has found this note ( Note : your security Code is the 4 digit number entered in your ' Car Audio Passport ' in this package ) but I didn't find any code in the package , so I called all vendors in Egypt to give me the operating code but they are refused
It is bad product
