Any help and advice much appreciated - i have a 2007 Pathfinder and just bought a secondhand original CD player to replace the old one which was broken. The screen says SECURE, i understand this is due to the stereo not being able to link up with the NATS as it came out another car.

Is there anywhere this can be reset other than a Nissan garage. I have contacted a couple of dealers and they havent even got back to me. Really liking the Pathfinder, but not to impressed with Nissan dealers so far!!

Any help much appreciated. I am based in Edinburgh, Scotland.
