Well, I finally got a full working copy of Garmin Mobile PC. Got my New Zealand maps loaded via Mapsource, no worries. Then went to search for an address... now I'm stuffed.
Stage 1, search for your "state". New Zealand is one whole country and has NO states, so map data has no "state" info.
Anyone got any ideas? Makes the whole thing a bit damn useless if I can't search for an address. I may well be missing something obvious, but I've had a good look thru the options. Currently still using nRoute.
