Then might I suggest downloading the maps for New Zealand from the Navman site. I don't own a Navman but I do own a Garmin and that's how I expand my map coverage. Cheers.

Mine was doing the same. Navman advised me to hook up to the computer and access the unit in my computer,
find my documents on the navman and delete the logs. Worked for me. However now I have another problem and Navman don't know who to fix it.

I have nz map for S90. Now I need European map.
I can send you nz map, maibe is compatible with your system.
