Where do I get maps for my Japanese import car?

From NzGpsWiki

Sorry, there are currently no New Zealand maps for Japanese import GPS systems in cars. Due to the fact that the New Zealand market is so small none of the makers (eg Sony, Panasonic, Kenwood etc) have produced New Zealand maps, the mapping format is also proprietary so no 3rd party maps have been produced.

There is talk of systems for New Zealand but this will require the replacement of the electronics in the boot (and potentially the replacement of the screens due to incompatible cables. For more information consult GeoSmart).

Best thing to look at if you are wanting auto-routing navigation in NZ (turn by turn instructions) is have a look at the Navman iCN 635.
