Humminbird Contour XD Map

I got the 788ci HD DI combo hooked up yesterday and started tooling around through the menus and screens. Was really interested to see wha tkind of detail the preloaded map (Humminbird Contour XD) had to it.

I can't get it to show contour lines at all. I had it set to show "All" detail and then moved my little cursor over to the lake I fish to see what I could see. All I saw was a white lake with no countour lines.

Any advice on how to remedy this? I am about 90% sure it is operator error on my part but I have searched and searched through the electronic manual and didn't locate a fix.

Sounds like your lake is not on this list.

After looking at the list it appears that humminbird went out of there way to include only the smallest, piddliest lakes in Kentucky and Tennessee. Kentucky and Barkley are not on the list?

Caveat emptor I suppose.

Next step is checking the lake lists at Navionics. If you got an android phone, you can get their app for $10. It'll be the same contour info as on the chip. That way you're not out too much money with a try before you buy kind of deal.

I bought the navionics app last week. I thought the contour detail on it was excellent considering the size of the screen of my phone. I actually used it to mark some spots and take pictures after my old Harmon unit quit working and before the humminbird unit shipped.

I bought the navonics card for my humminbird because of same reason. I also have it on my phone and pc.

Probably some deal they made with Navionics. The mapping company doesn't want to include all the lakes, otherwise you wouldn't have a need to buy their product. H/B used to offer the full mapping, but at a much higher cost to buy the combo unit.

The ContourXD map data is from Navionics as was the NVB mapping data. I will assume that you are also correct Shellback in that if they sold us (and kept it updated) all of their map data that they would not be able to make additional map card sales. The flipside of that is also that the cost of the units would have to increase to cover our cost of all that map data. You would than be paying more for a unit that has mapping data that you would never use.
