I recieved a Grundig WKC 3680, Part number: 93AC18K876AA and serial: 525010A0139890. I want to put this now in my company car, I recieved code 1035 with the radio, but I am on my 7th attempt and still the radio shows SAFE on the display. What are the waiting times and how do I enter the code, or can somebody help me with correct code maybe or tell me how to retrieve the code?This radio is made in South Africa.
