I noticed on the Webb App that contours are shown in the East Gulf area including Steinhatcheee, Florida. I recently purchased the Platinum card for this area and contours are not shown for this area. I refreshed my card yesterday and saw that the contours are still not shown. These contours are recorded as shown on the Webb App, then why isn't this available to our Platinum cards? I get the 1 ft contours for Tampa Bay, my local lake (Santa Fe Lake) and most other areas on my Platinum Card as shown on the Webb App. Why aren't these contours at Steinhatchee available to upload. The contours have already been recorded as shown on the online Webb App. I could get a lot more use of my Platinum Card if I could have all the recordings of contours that are available.
Does anyone know why this takes place. It takes forever to get a reply from Navionic.

Do you know that the Web App has the Sonar Charts contour lines as well as the Navionics map?
The round circle on the lower left of the app, turns the Sonar Charts layer on and off.

Do you have a Humminbird unit and do you know how to view the Sonar Charts layer with your unit?

I have a Humm 858 HD Di unit. I can see 1 ft.contours about everywhere using my Platinum card. It looks like the Webb App when looking at the contour lines, except Steinhatchee Florida area. I see them on the Webb App but not on my GPS unit. I scroll down to Tampa Bay and most other areas using my Platinum card and see 1 ft contours that look like the Webb App but when I scroll over to Steinhatchee I don't see the 1 ft contours. I see them for Steinhatchee on the Webb App but not on my Unit. I don't understand it.
