Quick x20 raster query

[franb]

If you add, for example, a WE map on an SD card to a 520 or USA/Canada map on an SD card to a 720 I know you only need the map folder on the SD card but what about the raster file for that particular map. Does that also need to be added to the SD card?

The raster file is only needed for when you zoom fully out and the unit then displays the raster image instead of the map, without it you will get a blank screen when you fully zoom out but if space is tight on the memory card you can leave this out if you want - Mike
