let me start by apologizing if this topic has been discussed. I have an Elite 9Ti and the C-Map Insight Pro card. I've been trying to set the custom depth shading with no success. I've tried searching the internet and watching some youtube videos but nothing seems to help. I tried calling Lowrance...and after a half an hour of being on hold with tech support i gave up. My issue is...whenever i set my custom shading depths they won't display on the map no matter what lake i choose. Whatever color i set my minimum depth shading too...when i exit out and enable on the map...the entire lake turns that color. I stopped by BPS and tried setting the shading on one of their units...it did the same thing and no associate to ask. Does anyone know if this is a Lowrance problem, settings problem, CMap Insight problem? thanks
