I have an imported Japanese spec Nissan 350z. Even though it has been regularly serviced by Nissan UK, it has a warning message on the SAT NAV system (which is all in Japanese and doesn't work - but that's another issue) telling me that I need to get the car serviced - when I don't. I understand that it is possible to reset the warning message using the buttons available - but all of the messages (and button text) are in Japanese. Has anyone else had the same issue and has anyone else fixed it? - If someone could tell me what to do, I'd really appreciate it.
