, but compared to the Navionics, the C-map is cartoonish. I find no way to get contours, structures..you know..the detail that I have in Navionics.
Is there anyone that can help? I did do the "update" via memory card, so , that wasn't the fix....
It may be that the C-Map you have installed is a “Continental” chart (North America for example) or other large region. The continental charts
have all of the vector data in them for obstructions etc., however they don’t display the details like a localized chart, which of course you would probably have to purchase
C-Maps customer service
has been pretty good IMO, I would suggest giving them a call and talking to a rep for a better explanation.
As far as details vs Navionics, remember that the “sonar charts” are mostly estimations built off satellite images
. We have found them to be fairly accurate though. C-Map shows some obstructions that do not show on Navionics in our experience.
Hope that helped some.
