Looking online it seems almost impossible to have a Japanese navigation system built into a car re-programmed to work in NZ, but before giving up I though I would check if anyone here knows how/if it can be done? I have found a place that seems to be able to do it, but only for certain models of what look to be high ened luxury cars. I have a 2007 Nissan Dualis, anyone know if I can get it converted to NZ maps somehow?
