Hi My son bought a KDC MP4036AX stereo off a guy from my other son work. He had a car accident and is in hospital at present. When we installed the stereo it goes into STANDBY MODE and unable to use. I dont want to bother him while in hospital about the code and was wondering if anyone could help please. Have contacted Kenwood and they want a heap to do. Isnt there a generic code for the system and if so could someone please let me know
