Last year, visited manawatu region. 

Trying to head north west to get to state highway 1. 

Garmin 660 directed me through this forlong road.

On the garmin map, it says that forlong road goes right through, but, you can clearly see on the hybrid satellite/road map that it does not. A river gets in the way. This cost 1 hour of driving.

So, I sent garmin a note to their map correction team ........  no reply, no nothing. And, the map is still wrong at the online garmin map viewer.  Even after they bought out the new maps. 

I bet, even after the next maps are bought out they will do nothing. 

This is why tomtom are better, they allow you to upload map much better. 

Garmin are one of those companies who use email as a communication disposal tool.
