My 89 Nissan Maxima J30 (imported from Japan) has a speed alert set to chime at 105km/hr. Speed limits on some of our highways are 110km/hr - it is driving us mad and no-one in the Nissan Service Centres we have approached knows where the alert adjustment is located - some have suggested behind the dash but cannot say where. My mechanic suggested I post this query on the web. I am hoping someone out there can let me know where this is located and how it can be adjusted (say to 115km/hr) or turned off. Thanks for your time.
