I got one of these units back in November, have been fairly happy with it but i've noticed the maps already have some errors or just out of date
eg. Maps don't know of the Avalon Dr bypass in Hamilton, nor the major round-about at Te Rapa being converted to Traffic Lights. Also a big thing that may throw it is when the Toll road between Orewa and Puhoi opens in a few weeks time.
Anyone know how often maps are brought out for navmans? (or can you load a 3rd party map into it thats more up to date?)

Cheers.
