Can anybody advise if it is better when applying the updated POI files to the Navman GPS using Custom POI feature in NavDesk software to "add to existing" or "Replace existing POI's".
I have tried to figure out the difference and frankly the only thing that I can see when adding to existing is that occasionaly when the lat long changes on any given PO you can end up with two references to the same POI - this tends to make the GPS a bit overreactive when informing you that you are approaching the POI.
