Topo Maps For Garmin GPS
I use these guys for updating the car gps.
They're up-to-date.... like weekly at times so if you want to find the latest subdivision, use them.
Only you guys will know re the topo's but I would bet they'll be in the same situation.
Lots of good info here about, gps-ish stuff too.
however, I'm guessing I bypassed the LINZ stuff as this was easier to utilise for me.
