Hi John, hopefully some useful information for you or anyone that is having difficulty in finding the codes for K12 or K13 radios combined with Sat Nav’s
Anyone with a locked radio/SatNav need to type in 0000 3 times which will bring up serial number, device number and date displayed on the screen.
This needs to be photographed along with the log book(as proof of ownership) and your driving licence, then email all the details to
gb@nissan-services.eu
Nissan will send the radio code through by email. Hope this helps
