I think Rich is just displaying the information in the file. If it's a raster chart then he's just showing the image, if it's a vector chart then he's displaying the various layers. I doubt if he has control over what's being displayed, as that's coming from the chart itself. Navionics should have looked at their chart and determined what the sounding units were, and seen if they matched the other units.

I agree that it's not fun when bounced from one side to the other and back again! Ugh!
