I was faced with a Nissan Connect system that was unfortunately unusable after a replacement gearbox was installed. Previous owners has not left the code in any shape or form. Contacting the selling dealer, the local Nissan dealer and the original selling dealer all proved unhelpful or unacceptable in one form or another. For instance, I live in Cornwall and the original dealer was in Cheshire. The only help offered was for me to take car into them and then charge me an unspecified fee. Radio Codes did exactly "what they say on their tin". I gave them details requested and within a few hours, I was supplied with a code which worked!!! This is a genuine consumer based, helpful company!!
