raster 250 maps

Steve - OziExplorer has the ability to automatically change maps when your position moves off the current map or across the map "neat lines". The "neat lines" (corner markers) are set up in "Check Map Calibration". Sounds like your map calibration files do not have the corner markers in the correct position which results in you plotting your position on the map border instead of the next map as you move. Read the help file in OziExplorer for more detail on corner markers and moving map.

If you imported the ecw calibration data into OziExplorer using the import function this would have caused your problem....calibration is OK but the corner markers will be on the edge of the actual image not the corners of the map.

Instead of moving all the corner markers yourself (If this is the problem) I would recommend you download the map (calibration files) for the Natmap series you have from the OziExplorer website. These will have the corner markers in the correct spot and your problem will disappear...hopefully.

I would not recommend going back to paper maps and a compass while driving...a bit dangerous and pretty inaccurate:)
