Ive noticed on my hds 7 touch that if I keep on 2d mode vs shaded. 2d shows all the reefs south of marsh island and the reefs in the pass.

Shaded looks like the pic of your unit that u posted. It shows the shallow and deep contours along with the contour line.

Yours maybe able to do tge Same thing
