The map works perfect on my nüvi 200. A friend of mine has a nüvi 765T on which it does not seem to work.
When viewing the world base map and zooming in, the moment the map switches over from the base map to the T4A map, it goes blank (white) with just geographical names shown (towns, street names). The name of the map is shown in the Map Info menu though, so I know it is recognized by the unit. Is there a compatibility issue with the nüvi 765T? I found a question of such nature in another forum, but no answer as yet. Could anyone with a nüvi 765 give it a try and report here? Thanks.
